My cat looks skinny but the vet says he's healthy. Should I worry?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Male | neutered | 5 years and 1 month old

My cat Choo Choo is a 5 year old neutered male. I've had him since he was about 10 weeks old. In the last few months I've noticed that his body looks as though he has been losing weight. He had his yearly checkup and vaccinations two days ago. I mentioned to the vet about my concern and even though Choo Choo is the same weight as last year and a little heavier than two years ago the vet said that he he felt that Choo Choo's body score would be about a 4. What can I do to get weight on him?

I would first want to rule-out a disease, or parasite causing him to lose or not gain weight. If the vet was not concerned about a possible medical issue, then I would not be overly concerned about her being a little skinny. The truth is that a score of four is not bad and lean cats are statistically healthier and live longer than overweight cats. Some cats (much like people) are able to naturally maintain a lean body condition. I suspect Choo Choo is one of those cats, but would urge you to discuss this with your vet before making any changes to his diet. At this time, I recommend feeding him normally and would not recommend a diet change until advised by your veterinarian. I hope that helps and all is well with Choo Choo.
