Failure to gain weight can be due to problems such as internal parasites, or even a result of metabolic or other illness. Checking for parasites in the stool is one way to tell, however some types of parasites may not be grossly visible. Bringing in a stool sample to your vet is the best way to have this tested. If there are no parasites present in the stool, your vet may want to examine your cat for any issues and may recommend blood work to check for any underlying problems. Feeding a complete and balanced diet appropriate for your cat's age and size can also help ensure he is getting enough nutrition.
