 If you have like a yappy dog, it might actually just sort of mess with the piece of an older cat. However, you know, it really depends, right? Because they might just find each other entertaining. It may be that the dog is good at leaving the cat alone when the cat doesn't want to interact. If the cat can just get up on the surfaces that it normally likes to and leave that behind, that helps too. So, yeah, I would say if you can just try a trial and error and see how that goes.
