The Wonders of Canned Cat Food

"You are what you eat" the old saying goes. Taken literally we can get a little carried away. After all, I am not a 5'5" chunk of string cheese (much to my husband's disappointment). Of course, we all know it means our bodies will be healthier if we fuel them with health food rather than junk food.

Pet owners have become extremely health conscious on behalf of their cats and dogs. They realize that the food Fluffy and Fido eat day in and day out must be nutritious and wholesome. Sometimes the adage "you get what you pay for" applies to pet foods but sometimes it does not. Consumers will be wise to remember that all pet food companies aim to make a profit through selling their product. Pet food marketing strategically plays upon our emotions as animal lovers. We want to feel we are doing everything possible to provide a safe and satisfying life for our pets.

Rather than take out a second mortgage on your home to buy that premium bag of dry cat food, please take a moment to read about a "revolutionary" approach to feeding felines. An approach that may reverse feline diabetes, reduce the incidence of urinary crystals and kidney disease, decrease food-related vomiting and allergies, and keep your cat lean and playful into old age.

The answer to your cat's prayers (even if he doesn't know it yet) is canned cat food. When I said this was a "revolutionary" approach I was being ironic. Canned cat food more closely mimics the diet felines evolved to eat--mice.

A mouse is a high protein, high moisture, low carbohydrate meal. Dry cat chow is a low protein (or mostly plant-based protein), low moisture, and through-the-roof-high carbohydrate meal. Eating an exclusive diet of dry cat kibble leaves the modern cat morbidly obese and chronically dehydrated. Obesity leads to diabetes, cancer, arthritis, skin problems, and more. Chronic dehydration assaults the kidneys, and triggers bladder diseases ranging from infection to crystals/stones to sterile cystitis. Poor quality or species-inappropriate proteins are claimed to trigger skin allergies and gastrointestinal inflammation ("puking cats"). Quality of life suffers as cats put up with discomfort on these many levels. Is it unlikely that some of this angst shows up as "bad" behavior?

I do not believe dry cat food is evil personified. However, kibble is just not perfect nutrition for the mighty feline hunter. It is a myth that dry cat food helps keep a cat's teeth clean. If you ate nothing but granola, never brushed your teeth and never visited a dentist...I shudder at the thought.

You may argue that canned food gives your cat the runs or makes him puke (this is usually a temporary problem during transition). Or worse that he doesn't like to eat it at all. Unfortunately, switching from highly-addictive carb-rich dry food to high-protein wet food is not always a simple task. Is it always easy to put down the bag of nachos and pick up a stalk of celery instead? Dry cat food is coated in a highly appetizing animal digest that makes kibble as tasty to most kitties as fast food is to most Americans (hmmm, is there a correlation?) It can take months to convince some cats that canned food is...well, the cat's meow. It took eight months and untold patience on his caregiver's part before my diabetic patient Tucker relinquished his dry food in favor of the canned variety. Lo and behold his diabetes improved practically overnight! Dr. Lisa Pierson, DVM's handout "Transitioning Feline Dry Food Addicts to Canned Food" is an amazing how-to manual on teaching cats to love canned diets.


Ounce for ounce canned food is more expensive than dry kibble. For those cat owners who spare no expense, it may be a small thing to re-allocate the money spent on the premium dry food to cans instead. For those of us who operate on a tighter budget, we can certainly compromise. Is it affordable and practical for you to feed one moist meal a day? Even just several canned food meals a week can improve the overall health, activity and attitude of your feline friend.

Some tasty tidbits:
1) Normal cat poop is not voluminous and stinky. Cats that eat quality animal-protein moist foods exclusively pass smaller, firmer, less odorous stools. If you've even seen coyote or raccoon scat in the woods, you'll understand what a predator's waste should look like -- including your cat's.
2) Cats did not evolve eating fish. They evolved eating rodents and birds. While most cats like the taste of fishy cat foods, try not to feed fish varieties exclusively. I haven't seen "mouse" or "sparrow" flavored canned foods in the pet store yet, so you will have to stick to "beef" and "chicken" for now. (Yes, there are frozen raw food diets out there that more closely mimic a cat's wild diet...more on this later.)
3) If your cat gets on board with you and eats nothing but canned food from here on out, make sure it is "complete and balanced". Canned foods labeled "for intermittent or supplemental feeding only" are missing essential vitamins, minerals and amino acids -- fine as a snack, not for a lifetime.
4) Wet food diets do present very real challenges in the mechanics of feeding. We have become so used to shoveling dry food into our cats' bowls that it seems like the natural thing to do. It takes more thought and care to keep moist food fresh and appetizing. One suggestion is to freeze several meals and put out two meals each day--one meal warmed to "mouse body" temperature and the second left frozen to thaw throughout the day.
5) A mouse is approximately 30 calories. Cool factoid, huh? The average wild cat eats 7-10 mice per day, which is the equivalent of 210-300 calories. And they burn a lot of calories actually catching, killing and eating that mouse! (Oh yes, cats that eat wild meals like mice should be dewormed regularly...just because something is all natural does not mean it is completely without negative side effects.) Check to see how many calories are in a single 8 ounce cup of your cat food...

Happy Birthday, Kitty!

People always want to know how old their dog or cat is in human terms. The rule of thumb for dogs has been one dog year equals seven human years, but we know that it not exactly right. Little dogs like Bichons tend to live longer than big dogs like Newfoundlands. Also the first few years of a dog's life are accelerated. A one-year-old dog is capable of reproducing and so it is definitely not the equivalent of a seven-year-old human (unless you believe those crazy tabloids)!

Unlike dogs, after the first few formative years of life, the ratio of cat years to human is about 1:4. As you can see, a feline surpassing 20+ years is deserving of a Willard Scott-esque birthday celebration!

Here are some tips for helping your kitty reach his or her "centennial" celebration.

1. Schedule annual wellness exams with your cat's veterinarian even though vaccines are not due. Most progressive veterinary clinics now booster feline vaccines only every three years. That's the equivalent of 12 years between doctor visits in human terms! Screening bloodwork should be performed periodically (and at least annually in senior cats) to catch certain diseases early. Early detection allows for easier management and a longer, happier life.
2. Spay or neuter your kitty to avoid medical and behavioral problems that may result in accidental death, illness or euthanasia.  
3. Feed your cat a high quality cat food but limit portions! Obesity is a huge problem in felines leading to diabetes, arthritis, heart disease, and skin problems from inability to groom. Most cats do not get enough moisture in their diets and suffer from GI and urinary problems as a result. Train your kitty early on to enjoy quality canned or moist foods. Dry food does not -- I repeat, does not -- prevent dental disease.
4. Dental disease is a common and painful condition in many cats, and it negatively affects their overall health. Ask your veterinarian for advice on how to prevent and manage dental disease in your cat. Just like people, most pets should have their teeth professionally cleaned (i.e., by their veterinarian) periodically.
5. Know what plants and household items are potentially toxic for your cat to avoid tragic illness or death. Also, PLEASE remember very few human medications are safe for cats. Some over-the-counter flea and tick treatments are OK for dogs but are deadly for cats!
6. Environmental enrichment can improve the quality and length of your cat's life. Many feline diseases are linked to stress. Learn as much as you can about feline behavior and play with your kitty every day. Especially in multi-cat households, make sure you have provided the proper resources for cats that may not get along all the time. A rule of thumb for litter boxes is "1 per cat plus 1." That means if you have three cats, you should have four litter boxes. Also properly placed scratching posts may eliminate the supposed need for declawing. By "properly placed" I mean in highly visible areas the cat has chosen, not the owner!  

Sadly, even with proper care and the best intentions some cats do not live to ripe old age. It is no different with us humans (I'm thinking of the fit and trim 30-somethings who die tragically from cancer or accidents). However, cats who receive proper exercise and nutrition, regular medical and dental care, and environmental enrichment will have an improved quality of life no matter how many candles are on their tuna cake.

Kick the habit and other ways to prevent cancer in your pet!

Animal companionship has a proven positive influence on our general health. Numerous scientific studies have shown that caring for a pet actually improves our health by reducing stress levels and increasing our physical activity.

Unfortunately, we and our pets also have a lot of diseases in common -- cancer, diabetes and inflammatory disease -- that are often directly linked to negative lifestyle choices.

Kick the Habit
Cigarette smoke is a long recognized cancer-causing agent in humans. The risks of second hand smoke to other people has led to smoking bans in all public places in Wisconsin over the past few years. News flash! Research shows that second hand smoke causes cancer in pets, too. Squamous cell carcinoma (SCC) is a common cancer in cats. It often occurs on their face or in their mouth. The development of SCC on the lips, eyelids and nose has been associated with light-colored cats that love to sun-bathe! The form of SCC that occurs in a cat's mouth responds poorly to treatment and has been linked to ingestion of cigarette smoke from the fur. Cats are fastidious self-groomers, so they are exposed to a lot of cigarette chemicals this way!

Second hand smoke is a cancer causer in dogs too. Whereas the carcinogens inhaled in cigarette smoke settle out by gravity in human lungs, in dogs these cancer-triggering chemicals are filtered out by the delicate canine nasal tissues and create tumors in the nose. In fact, the longer the snout -- think greyhound vs. pug -- the bigger the risk of developing nasal cancer.

Shed some Lb's

Obesity increases the risk of many diseases in people and pets. Fat dogs, for example, suffer from debilitating orthopedic diseases. For years we veterinarians have preached weight loss in cats, for example, to prevent and manage diabetes mellitus. Now cancer researchers have connected the dots between obesity, diabetes and cancer. There is an elaborate Rube-Goldberg-type biochemical chain reaction to explain the link, but the "Chemistry for Dummies" version goes something like this: high carbohydrate diet (especially processed sugars) è increased blood sugar è increased insulin receptors è obesity and inflammation è cancer.


We can break the links in the chain any number of ways to reduce the risk of cancer in ourselves and our animals. Changing our diets to significantly reduce highly processed carbohydrates. Bam! Shedding that excess weight. Bam! Reducing inflammatory processes in our bodies. Bam!

A natural dietary supplement that is being used in human and veterinary medicine for a variety of beneficial purposes are polyunsaturated fatty acids. One way fatty acids benefit animal health is by reducing inflammation (in the skin, joints, gut, etc.). Fish oil and algal sources are appropriate for pets, but don't bother giving flax seed sources to Fido or Fluffy because dogs and cats cannot metabolize flax to access the beneficial fatty acids.Your veterinarian can help you determine a fatty acid dose for your pet (it's higher than you think!).

When it comes to being susceptible to cancer -- whether you walk on two legs or four -- genetics and environment are intimately linked. Many of the lifestyle changes recommended by the American Medical Association over the years to improve human health also improve the lives of the animals who share our homes and hearts! If you don't do it for yourself, maybe those pleading puppy dog eyes or that purr of contentment will convince you to make that one vital change.

Help! I turned my back for 3 months and my dog got FAT!

EdGrrr the Athlete, 2007

EdGrrr, my 6-yr-old Labrador retriever, used to have the body of an athlete. No. Not just an athlete. A marathon runner. He was lean and mean. He had a lovely hourglass figure and was he ripped! Some people thought he was too skinny because, unfortunately, the breed standard for Labradors has been a somewhat thick and chunky variety of dog. While I battled baby bulge myself, I was so proud of my young lab's fitness and physique.

Then this summer, while I was building my vet clinic, EdGrrr went and got fat. And not just fat, but I-finally-weighed-him-on-my-clinic-scale twenty pounds fat! I'm not sure how I missed it, but now that he is chubby it has been a true challenge to whittle away the pounds.

EdGrrr the Tub, 2011

Although I have always measured my dogs' food and fed twice daily meals, avoided people food and shied away from regular treats, EdGrrr had plenty of help in the additional calorie department. His chummy personality and eager expression earned him a sandwich (or two) a day from members of the clinic work crews. Of course, I didn't learn this until after the work was done. To be fair, they played more fetch with him in three months than he's had in the previous three years.

I can't blame the workers entirely for the obesity-fueling excesses. EdGrrr, a farm dog through and through, finds calories in the darnedest places: a little grain from the feedlot steers here, a few compost heap veggies there, and a dead deer for dessert. I'm starting to feel like EdGrrr will foil my best efforts at dieting him no matter what I do.

So in spite of my failure at keeping my own dog at a healthy weight, here are some tips for your pet's diet:

1. Feed your pet distinct meals each day rather than keeping the bowl full. Many pets just can't resist another trip to the all-you-can-eat buffet. (Sound familiar?)
2. Use a true 8-ounce measuring cup to feed a precise amount of food as directed on your pet food bag (or by your veterinarian). The range on the pet food bag is often quite broad (such as "For a 40-60 lb dog feed 3-5 cups per day") so you will have to use your best judgement. Remember the amount is the total daily amount and you will have to divide that by the number of meals you feed a day.
3. If your pet is on a diet, make sure that you are feeding an amount meant for her ideal or goal weight, not her current weight.
4. Make sure chubby is on an adult maintenance diet (see Nutrition 101 for help selecting a pet food). "All life stages" foods are essentially puppy/kitten diets and won't help an obese-prone pet lose weight.
5. Watch the people food. It's really hard to gauge how many extra calories are being consumed by pets that lick the plates clean after dinner or receive tasty tidbits from Mom, Dad or human siblings throughout the day. Some types of people food are outright toxic for pets, so best to avoid it altogether.
6. Go easy on the treats. Of course you can still give treats. But your pet loves receiving a gift from you not the gift itself! So, if you can break that Milkbone biscuit (a doggie "candy bar" incidentally) into smaller pieces do it. Or choose a low calorie treat; the pet stores are full of them! In the really hard cases, you should eliminate treats and just offer a few pieces of your pet's daily allotment of kibble (chances are he won't know or care it's just his regular food).
7. Exercise. Enough said.
8. Once you've made one or more changes to your pet's diet you can weigh her periodically (say, once a month) to monitor progress. If your pet is small enough and you have a bathroom scale at home you can weigh her by holding her and then subtracting your own weight. For bigger animals you may need to schedule a weight check at your veterinary clinic (there probably won't be a charge for this...just ask!)
9. If your pet is not losing weight and you've really -- and I mean, really -- implemented the above tips religiously, please have a chat with your veterinarian. There are several treatable medical conditions that cause unrelenting obesity that can be diagnosed with a thorough examination and blood tests.

As 2012 dawns and I make my own New Year's resolutions to eat better and exercise more, I vow to get EdGrrr to a healthy weight as well. I may not have his full cooperation, but I do know that if I go out jogging he will be my willing companion. Then I can at least cross #7 off the list!

Have a wonderful New Year!
