The main reason for feline obesity (as well as obesity in other mammals) is the consumption of too much food. Deny it all you want but it is a fact.
What we do…
Many cats are fed “free choice,” which means there is food available all the time and the cat eats whenever it wants. (Pretty unnatural for a true carnivore that evolved as a hunting machine!) Free choice feeding has probably been the biggest single factor contributing to feline obesity.
What we should do…
Feed two to four small portions daily and control the amounts fed so that over a period of time the cat does not gain weight. Many pet owners must downsize what they think is a “normal” portion. A meal for a 175-pound human might weigh 16 to 24 ounces. A seven-pound cat weighs 1/25 of the 175-pound human.
So a cat’s meal should proportionally be about 1/25 of a human meal. That comes out to between 0.6 and 1.0 ounce of food per meal for a seven-pound cat… about the same weight as a mouse. Cat owners must stop thinking in terms of “cups of food” and start thinking in terms of ounces of food.
