As per the title really! What do your cats do when they see a 'stranger cat' outside through a window? By stranger cat I don't mean one that's slightly odd but one that's not part of their household!
Riley and Lu are 2 1/2 now and have always been either indoor only or have only had access to their catproofed garden. There's not very many cats around here, especially given that the neighbouring gardens on all 3 sides are patrolled by dogs
so don't think they've ever seen another cat in the flesh on home territory. They saw other cats in the cattery and didn't seem in the least bit bothered by them, I asked on here at the time and people thought it wasn't indicative of how they might be with other cats in general though as it was a strange environment.
This morning there was a cat in my front garden (ripping my bin bags open as it's bin day
). I lifted Riley up to the windowsill so he could see it and there was no puffy tail, no growling/hissing - just a bit of a tail swoosh, almost as if he had seen a bird. He lost interest in the cat quite quickly too, as though he wasn't affected by the sight of it and is acting completely normal not on high alert or anything.
So... How does your cat react? Does it sound as though Riley might be cat friendly? I didn't show Lu as he is very sensitive and was worried about him feeling threatened
