Transitioning Dry Food Addicts to Canned Food - Pt 2

This is the first, and very critical, step. You need to establish set mealtimes. They are not going to try anything new if their bowl of junk food is in front of them 24/7.

Cats do not need food available at all times. It really is okay for them to experience a hunger pain! That said, it was very hard for me to listen to my cats begging for food even though I was strong in my conviction that I was heading them in the best direction for optimal health. It truly was a stressful time for me and them. Actually, I think it was harder on me!

This is where many people fail and just give in and fill up the dry food bowl. There were a few times when I had to call my 'sponsor' and was instructed to "just leave the house if you can't take looking into those eyes!" I left the house. Those pitiful little cries of "I have not had food for two WHOLE hours!" were hard to take. But, lo and behold, they were just fine when I returned. Not one cat had died from hunger.

On the other hand, do not attempt to withhold food for long periods of time (greater than 24 hours) with the hope that your cat will choose the new food. You need to ‘convince’ them that a high quality canned food really is good for them, rather than to try starving them into it - which does not work anyway. Allowing a cat to go without food - especially an overweight cat - for a long period of time (greater than 48 hours) can be quite dangerous and may result in hepatic lipidosis (fatty liver disease).

Hepatic lipidosis can also develop when a cat consumes 50% or less of his daily caloric requirements over a period of many days. The definition of "many" varies from cat-to-cat. For this reason it is important to understand that you need to have some idea of the calories from canned food combined with the calories from dry food that your cat is consuming on a daily basis while you are implementing the transition to canned food.

I have never seen a cat develop hepatic lipidosis when consuming at least 15 calories per pound per day. This number is figured on lean body weight, not fat weight.

If your cat weighs 18 pounds but really should weigh 12 pounds, please make sure that he is consuming ~180 calories per day. (12 pounds lean body mass X 15 calories/pound/day = ~180 calories/day)

In reality, the cat in the above example would probably be completely safe at only 150 calories per day.

If you have a small female cat that should only weigh 9 pounds, please make sure that she is consuming at least 135 calories per day.

Canned foods never list the calorie content on the can but many dry foods do list this information on the bag. A rough guideline for the calorie content of most canned foods that are 78% moisture is ~30 calories/ounce but can range from 20 to 40 calories/ounce as shown by the chart linked above.

Most cats will lose some weight during the transition to canned food. Given that a very high percentage of cats are overweight to begin with, this is a favorable result of the diet change - as long as they do not lose too much weight too fast. A cat should never lose more than 1-2% of his body weight per week.

I highly suggest that all cat caregivers weigh their cats periodically especially if they are over 10 years of age. This will help ensure a safe transition to a healthier diet and, in general, weight loss is often the first sign of ill health for any reason. I make it a point to weigh my cats at least once each month especially since they are now over 10 years of age.

Here is a scale that is reasonably priced: Salter Baby and Toddler scale. It weighs to the nearest 1/2 ounce and has a 'hold' button on it that helps obtain an accurate weight even for a cat that is moving around a bit.
