All right, I saw that this topic had zero posts, and felt sorry for it. So here's the great (or not so great) addition to keep this topic from feeling lonely. I have two cats, a tabby and a manx, both males. The manx, obviously, is SUPPOSED to be big. The tabby? Not so much. But they weigh 17.5lbs each. Yup. BIG cats. I was beginning to think I was spoiling my tabby when I noticed the other day that he was pushing over the Manx and finishing off both bowls of food! Oy. So the Tabby, JR (not after Tolkein, but I wish!), gets fed in the bathroom now. I get to enjoy a pair of yellow green eyes while . . . yeah. My vet says "he needs to go on a diet". I give the manx normal cat food, the tabby the diet stuff. But I discover an anomaly-now my Manx is the one pushing over the tabby for food!! He likes the diet stuff so much he's abandoned his own bowl, learned overnight that he was big enough to push over the tabby, and is eating his food!! So now they are both on diet food and quite content (all right, JR isn't, but he's a little annoying and overweight, so I don't really care!). And want to be fed all the time b/c diet food will never have exactly what they need and they are always hungry.
