Pretty (a male) normally stayed in the yard. he would come in and go out when someone else did. For three days now he has been going somewhere and coming in badly scratched and beat-up. The first time I thought a dog attack, but today he is bleeding from scratches to his ears and bites on his neck. He is spayed. Why is he fighting? He's not really an outside cat. And he is over 5 years old. Any ideas on how to stop this would help.(other than keeping him prisoner). And he has caps on. Thanks
