Q. I have two cats but only one is over weight the other one always throws up if he eats to much food how do I get one catless fat and one not to vomit .

A. If one cat keeps throwing up from eating too much you should feed small amounts more often. The other cat needs to be fed separately and possibly also less food split up into three feedings. I suggest you feed wetfood (canned food), each cat gets 1 4 oz can divided into 3-4 feedings over the day. Feed them at the same time but in separate places so the fat cat cannot steal the other cat's food and the throw-up cat can learn to take its time while eating. Also play with the cats, to get them to exercise (throw paper balls, etc). There is also a commercial diet food to help with weight loss.
