We'll the cats started spraying again!(healhy cats) Would love to keep them inside but I cant handle it anymore. They spend most of their time outside in the summer time, but its cold here in Minnesota and they spend very little time outside this time of the year. Well they are gonna go outside weather they like it or not. Ok does anyone sell a insulted/heated cat house that i can put in my garage. or heck i'm pretty handy i can build them one if i had some good plans. Or if anyones got anygood suggestions I'm all ears. FYI I searched the forums for spraying so I have all that good info to work with as well. thank you in advance.
