I think we might call him Jimmy, that's pretty cute. Our cat Marla is growling & hissing at him and he just seems confused and nervous about her. She always lived with other cats for 7 of her 8 years of life, though, so she'll get over it eventually. I think she's feeling territorial. I ordered some Feliway online, I heard it might help.
He is a sweet boy who rubs all over you for love and flops on his belly to be petted. He has his claws though, and he's already tried clawing our couch a few times. I got him a scratch pad but he doesn't seem interested in it. If he keeps trying to claw our furniture, he's gonna have to have those little claw cap things put on him. I don't remember what they're called.
