My freind has a problem with coons and cat getting in his boat when it is stored. He use to to catch and release but they would always come right back, mostly the cats. he has come up with a way to deture them from coming back. works on coons and cats. pressure washer. As long as you have them in the cage clean them up a bit. 'the cats never come back and the look on thier face is pricless.
