If this grumpiness is a recent development, he may be hunch out of sorts. If he goes outside, he may own picked up a parasite or gotten into a fight. Cat bites are not other easy to see contained by their fur, and they frequently become infected and turn into abcesses, which would make anyone grumpy. Take him to the vet for a check up in the past doing anything else.
you could dispose of him.....
Have u had him neuter yet?? Apparently this settles a cats hormones an relaxes them more.
