When we first got Bella, she ran right up to our old cat Hollis and got right in his face. Hollis, on the other hand, tried to keep his distance until he could figure out what manner of creature we brought into the house. Sure as can be, as soon as we brought home Killian, Bella did the same thing Hollis did. I guess it’s only natural to be suspicious of new things that make noise and move very fast.
