how do you keep cats out of your barn? My barn is starting to stink pee. I do not feed them as I think they can live off of mice at the barns, there are 40 barns where we are. Some people feed them so I don't as I don't want them to not eat mice, but I find I am smelling a pee smell in the barn once in a while. The barns are not built to keep them out, so can't lock them out. Any suggestions. By the way the horse is still spooky , but seems to be getting better. I ordered the book how to train a spookmy horse, so hope that helps too. Thank=you everyone for your advice. Have a Great Day, Corrie
