I have two cats, Greg and Gladys, who live outside on a large screen porch. This arrangement has worked well for a year and a half, but now a new stray, intact tomcat, Oscar, has shown up and is causing trouble. He pees all over the place outside the porch, and Greg has started peeing inside in retaliation.
Oscar is basically friendly, letting us pet him and scratch his head, but goes ballistically violent if we try to pick him up. Therefore, none of the shelters will take him except for county animal control, who told me honestly that they would euthanize him. And I don't know any people who would want to adopt a cat like that.
My only recourse is to get him neutered ASAP, put him back out, and try to socialize him better so he can eventually be adopted. What are the odds of the peeing behavior stopping? I've read that only 10% of neutered toms continue territorial peeing, but I don't know if that applies to half-wild outdoor cats. Thanks for any advice/info.
