Well, I can attest to that. Probably wasn't helpful that the previous
cat was house-broken to a degree that it always came back _in_ for its
cat box. Though once the horrible, horrible kittens were roaming the
premises, he did no longer venture outside at all.
First time the female kitten paraded before the patio door, the big cat
easily three times its size panicked and did a running start like from a
Warner Bro's cartoon with wild sliding on the spot, hitting several
table legs like a pinball game ball, then rushing up the staircase and
ducking down at its top, peeking down trembling.
Pathetic. The roommate moved in with her boyfriend who has an old
tomcat and several dogs. Apparently now her cat is dominating over the
whole household and feared by cat and dogs alike. But at our place, it
was completely hopeless.
