Our Benjamin is a late neuter. When we rescued him from the pound he was still a hob. We wanted to let him get used to us and settled before we arranged his surgery. A whole hob is a whole lot of fun! He marked our shoes and rugs...he was one stinky boy! But he has never been really aggressive due to being a late neuter. He will strike at you if you startle him, he is also blind. Than has gotten me bit a time or two, trying to pick up a sleeping Ben. Now I talk to him before I tough him. He still might be asleep, but it seems to help him to anticipate being touched and there hasn't been any trouble. It sounds as if the issue might be the rubber gloves. Years ago when we first rescued Dunkin, he would freak out about gloves of any sort. That lead me to think he has been abused or roughly handled while someone was wearing gloves for protection. My husband is a motor cop, so gloves are a part of the uniform. He learned quick not to pick Dunkin up when he came home as long as the gloves are on. Good luck with the boarder.
