Our older cat really doesn’t cope well when we go away - he cries all the time and cries for days afterwards too. Our lovely cat sitter said she thought he would benefit from cat company. A friend had rescued three kittens (found by the side of the road - their mother had been run over and killed) and asked us if we would like one. We said yes - we previously had a kitten, and he loved her (unfortunately the love was unrequited and we rehomed her after four years as she just wanted to be left alone and not washed and cuddled all the time, which is what he wanted to do).
It’s been a week now, and he has started hissing and growling at me when she’s not around. He hasn’t attacked her, but hisses and growls at her when he sees her. We had an uneasy truce last night when they were both on the bed together, but it’s got worse again this morning. When she’s not around, he’s his usual cuddly lovable self, but when she’s around he is aggressive to me as well as her.
A friend of mine had the kitten’s sister, and would take our kitten too. Are they never going to get on, or should I give it longer? And if I give it longer, how much longer? I just want to cuddle him, but he’s having none of it.
