Cats do get used to dogs.
Over the years our cat/s have got used to Great Danes, Wolfhounds, Ridgebacks, and Staffies.
Pecking/scratching order is quickly established in favour of the cat.
Our current aged cat has had more trouble adapting to my daughter’s 2 young cats which have just been dumped on us while she finds a new house.
I don’t agree that cats don’t care. It’s just they show it differently.
Our cat follows me and the Wolfhound out for a walk. She’ll go for about a mile and comes to a close approximation to heel if I whistle. Previous cats have done the same, and it’s off their own accord. We don’t try to get them to come along.
