Hi my black neutered tom is fighting when he goes out. He is coming back with large bites and missing fur patches. The latest is v. nasty. We are worried that these bites could get infected but if we put any antiseptic on them he will just lick it off won't he? Should we take him to the vet? The problem is this stresses him out and we don't want to do it every time. We moved here 2 months ago so I'm guessing it's territory related. Can anyone give us some advice?
