Now, 10lbs is considered a healthy weight for a full-grown domestic cat. He looks very healthy, he isn't thin at all. He's very muscular. The general consensus seems to be that 1/4lb (4 oz) is the proper amount to feed daily to maintain his weight, so that's how much I feed.
However, he acts like he's always starving. He gets onto the counters to find whatever scraps he can - he'll eat ANYTHING. He even eats my roommate's cat's food (a prescription diet kibble) so we have to put her food bowl into the cabinet when he's out. I have been trying positive reinforcement via treats to keep him off the counter (we have a glass top stove that stays super hot, plus my roomie has a bowl of garlic on the counter and I don't want him to hurt himself with either), but he's very insistent. After I feed him, he will meow at me and bite me in an attempt to give him more. I can't tell if he's just gluttonous or actually hungry.
What do you think? Should I be feeding him more? I have been thinking about increasing his portion to 6 oz per day, but I'm not sure if I should.
