I'm so sorry to hear Mr. Magoo turned into a savage beast on you! I'd go to the store and get some Epsom Salts and hot soak your hand several times a day to draw out any toxins. And you may want to look into getting Magoo some "Rescue Remedy" http://www.nelsonbach.com/rescueremedy/ Which may calm him down. I have used it with great results on a Himalayan girl I have here. Mewsette is one very cranky cat, and putting R.R into her wet food seemed to work wonders. It is for people who are stressed out and wanting to choke someone! R.R is available at health food stores, and it doesn't take much to work. Mewsette gets it when she starts turning testy with me. She has tried to bite me, and scratch several times, but my reflexes are fast from years of feral kitten taming! How long ago was Magoo neutered? Could be he still has a lot of hormones in his system and the combination of smelling the outdoors, and being in a new environment set him off. I'd probably move him into a separate room and let him start making the first moves rather than you. And leave the windows shut for a while so he doesn't feel that wanderlust, smelling the air! Classical music soothes the savage beast too! Hang in there...we're all rooting for Magoo!
