If you are what you eat, then it should follow that your
cat is what he eats. Most prepared cat foods on the market
today have been nutritionally balances, so look for labels
that say “complete” or “balanced.” However, you may want
to supplement your feline’s diet with some extra snacks.
Often pet owners wonder whether they can give their cats
table scraps. It is a grand idea, depending on what the
scraps are. The rules to follow are: Never give your
cat anything you would not eat yourself. And never give
your cat more than one-fourth of his total intake from
the table. Too much an upset the nutritional balance of
commercial cat foods. Cats enjoy milk (but remember it
can act as a laxative), eggs, meat, fish, broths,
vegetables and cereals. If you notice your cat eating
grass, or your houseplants, he needs roughage in his diet.
Feed him the same kind of rough-age that you would eat
yourself—spinach, string beans, etc.
The cat’s calorie requirements decrease as he grows older.
Also, it is generally agreed that neutering does not cause
over-weight, but too much feeding does.
