My senior cat is losing weight, not eating, and vomiting. See a vet?

Pet's info: Cat | Maine Coon | Male | neutered | 16 lbs

My cat Harley is 20 yrs. He is starting to lose weight and no longer has a big appetite. He throws up occasionally. He uses litter box regular and everything is good there. He sleeps a lot and doesn't enjoy his catnip anymore. Should I make a appt with his vet to have them do blood work and see if and what kind of health problem there may be.

Hi there! Yes, I would definitely suggest taking Harley to the vet for an exam and some lab work when you get a chance. It's common for cats to develop health issues as they get older, like chronic kidney disease or hyperthyroidism, that can cause appetite changes and weight loss as well as occasional vomiting. Some of these problems are very treatable with medication, so it's worth trying to get a diagnosis if you can. Your veterinarian should be able to advise you on what treatment options might be helpful depending on the results of his blood work.
