Our six-year-old male cat, Cairo, has become increasingly aggressive and antisocial over the past year. Specifically, he has targeted our neighbor's cat and has attacked him (at their home)several times, at leat once quite viciously. The neighbors have armed themselves with a water gun that they use when he comes on the property, but that no longer works and the attacks are getting more brazen. Interestingly, Cairo is tolerant of our other two cats (male and female) as well as those of our tenants and neighbors (and one of those is an unnuetered male, the cat that is). Cairo just has a thing about the neighbor's cat, which interestingly belonged to the previous owners of our home and stayed here with our previous tenants before they moved (and Cairo was fine when the cat lived here).

I cannot keep Cairo indoors as I don't trust him with our children. Cairo can be very loving and friendly, but he can just as easily turn and attack without warning. Moreover, he is absolutely miserable indoors after an hour or so. Cairo is simply very, very unhappy. He comes in for meals, but gets stressed and leaves. His schedule is very erratic so kitty prozac is not the answer. He's the feline equivalent of a mentally ill homeless person that won't stay in a shelter or take his meds. Declawing will not likely help, either and in fact may make him more aggressive. On the other hand I need to do something before he seriously injures the neighbor's cat (or we get sued!).

Any ideas? Does anyone know of a farmer that needs a good mouser (Cairo is a good hunter and I will happily provide suupplemental caright, but I also cant food)? I have actually contemplated euthanizing the cat, but it is a heartbreaking option I cry just to consider. Your thoughts and suggestions are welcome, online or off, as I've run out of them on my own. Thank you.
