Hi there.

Older cats with a good appetite commonly get a hyperthyroid condition that causes them to become very thin even though they are eating. The best thing you can do is to take your guy into your vet to check his lab values, If he is hyperthyroid, the treatment is simple and this will help him gain weight.

If he is not hyperthyroid, then this is due to your cat becoming older. the digestive tract in older cats becomes less competent and they do not take in all the nutrients that they take in. IN this case, you have to feed him more often with higher calories.

Good Luck!!
