Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. First off, I would ensure he is eating enough food. If you are feeding adequate amounts of food and he is still not gaining weight, I would be concerned about a metabolic / endocrine disease such as hyperthyroidism or another systemic illness / infection. Unfortunately, if you are feeding him adequate calories and he is still not gaining weight, the only recommendation I can make would be to have his blood tested to see if he has hyperthyroidism or some other systemic disease. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
