Our cat was about 8 when we bought our Akita. They get along OK, although the cat (now 14) isn't exactly thrilled by his presence. She was used to my other dogs who usually tried to get to know her once, got scratched & gave up. The Akita never even noticed if he was scratched, so didn't give up & tends to be very much 'in her face' which she doesn't appreciate.
I wouldn't trust him an inch with other people's cats tho'.
