Male Cats In Heat?

Ok last night Fluffy was with my dh and my dh was petting him and stuff. Fluffy got up and there was wet spot on dh arm. TMI Is Fluffy in heat per say?

Sounds to me that Fluffy got excited & had an oops on your DH's arm!
Is he neutered?

If this happens again, smell the wet spot (I know, gross, but you know what urine smells like). My guess it was urine. If this persists, a checkup by the vet might be in order. Male cats are prone to urinary tract problems. Also check that he is not urinating frequently or straining while he goes.

I would say that you need to watch Fluffy and see if there are any litterbox accidents. You may not know if he is finding elsewhere to pee. He could have a UTI which left untreated can become quite threatening.
