My vet told me to put my cat on a diet (1/3 cup of Iams Weight Loss a day) about a month ago b/c he's got a little saggy pouch between his back legs. I am worried though, b/c he's only 6 months old and has no other signs of weight gain - I can barely feel his ribs when I run my hands along his sides, if I stand over him and look and him from above, his little figure looks like they say it should, etc. My cat is devouring the 1/3 cup of food a day and begging for more. Am I just being weak or should I really go back to his normal food schedule (1/2 cup of Iams Light a day)? I haven't really noticed much weight loss, maybe a little. Is it OK to put a kitten on a diet? Should I get a second opinion?
