My puppy had never really been around cats but he's very good with my bengal. (lol yes it's a cat not a tiger I don't think they allow tigers in lofts.)
Also I work with a trainer who trained her dog, whom she just got from a rescue who used to eat cats to sleep with her 3 cats she currently has.
It was a miracle
she's like the dog whisperer lol
I've seen her work with the most aggressive dogs and they turn out to be the sweetest pets ever!
