I have a neighbor cat that is spraying on my coop. I work hard to keep my coop from smelling and this is not helping. The cat is obviously not fixed and in addition to marking 'my territory' it is courting neighborhood female cats. I feel strongly that responsible cat owners should spay/neuter or keep their pets inside. This world does not need any more unwanted kittens, and I don't need the funk. Does anyone have any advice? My best two solutions so far involve the neighbors not having a cat anymore.
