My cat is lethargic, vomiting, and has a low temp. Should I go to vet?

Pet's info: Cat | Domestic Shorthair | Male | neutered | 7 years and 10 months old | 15.4 lbs

My cat eats well, but sleeps more than usual and more “lifeless”. His temperature is 36.8 celsius...is this a normal temp? He did throw up yesterday morning as well. Should I take him to the vet?

This temperature is slightly below normal. Normal temp is 37.7 to 38.8. We can sometimes see the body temp be a bit below normal when their blood circulation is less not as good as it should be — most often we see this this due to heart disease or dehydration. If he is very dumpy and lethargic (which is what I assume you mean by “lifeless”) and recently vomited as well, please take him to your vet. They may recommend blood tests and possibly xrays. Treatment will depend on what they find on exam and any testing.
