in my chin room i also have a cage with two ferrets, when the ferrets are out for playtime, the door to the room is closed.. no ifs ands or butts...
i have 2 dogs that are not allowed in that room, i have a gate up and cairo respects it, [bears needs to learn to respect it, he's just a pup]
i have two cats, cali respects the gate, kitten doesn't ugh.. anyways, be careful not to let your cat scratch your chin, that can be harmful.
also, make sure you have a door that can not open unless you open it. story time: once upon a time.. jean had just one chinchilla... she put him back in the cage for the night and checked the door and it was locked shut [the way cage doors clip shut, not literally a lock]. in the morning jean gets up for work and when she goes in the other room to get cairo to put out, she sees chinny fur all over the floor, and i mean ALL OVER THE FLOOR . SHOULD I SAY FLIP OUT TIME. i thought he was dead.. i was so upset. i thought i left the door open or something.. anyways, i put cairo in the yard, i go in the chin room [i will never forget this] and chin chin comes hoppin in.. almost like nothing happened.. of course i was happy as he## to see him.. his back was scatched up, i knew what happened, cairo was trying to play, and pawed him, chinchin released a ton of fur for protection [which at the time i didn't know they did] and his back got a bit scratched, but luckily not bad. anyways, after all is said and done, i do think it's funny that once cairo went out in the yard, chin chin was like.. it's safe i can come out from hiding now.. and hops out of his hiding place. too funny..
anyways, i found out, i didn't leave the door open, the little stinker got it open himself and got out... so be very careful especially with other pets than can harm him...
