I am a charmer. Tanner wasn't taken back at all when brought to his foster home that included 3 other cats. No hissing, growling, just lots of sniffs and then playing. However he wasn't so sure on the bigger thing though when he was introduced at the door to his foster Shepherd sister. A few big growls and hisses came out at first, but after time to adjust to his new surroundings and companions ( about an hour), he was fine especially when he discovered the magic appearance of leftovers.

So far his favorite place to be is on the counter by the window so he can watch everything outside yet keep close tabs on his fosters brothers to make sure he isn't missing out on play time... which he joins right in on... still a bit unsure of the dog, and only gets a bit unsettled when she runs around with her squeak toy, they even slept in the same bed for a nap...
