We had someone else’s cat staying with us and our three cats for a while. They never fought, but our oldest hated the “guest” and vice versa. I caught them once, one on a desk and the other on the chair, just loafed up and occasionally growling and hissing at each other. I have no idea how they ended up together, but neither of them wanted to move. It was pretty funny to watch.
This ended with Lorelei lunging at Rocket, grabbing her by the neck and trying to bite her.
Rocket is 10 years older and just is… not… playing…
We have Bunny(11) and Korra (3); Bunny hates Korra and they’ve lived together since Korra moved in at 8 months. Korra just wants to play and snuggle, Bunny ain’t got no time for that.
That’s what’s hilarious to me… we brought Lorelai in at about 6 weeks, Rocket hated her instantly with the power of 1,000 suns, but our 3rd cat, Keanu, loves her. They are best buds.
But when we got Keanu and he was a baby and Rocket was 2, it was the exact same reaction.
Major sibling energy.
