I'm absolutely heartbroken writing this.
We adopted a cat back in 2020 from the RSPCA. He is very timid and skittish. I have always wanted two cats but once we got my boy I decided he wouldn't do well with another cat so we left it. Then last year our neighbours cat started coming into our house and my cat was fine with it! He was so chill about it, I was shocked. But it made me think oh he must be fine then maybe we can get another after all.
We recently got a kitten as I thought a kitten would be less threatening. We watched all the videos on how to introduce properly and slowly and we have followed it completely. My cat is NOT happy. He won't come near me, won't sleep in any of his usual spots, doesn't want to come inside and when he does he spends most of the time crying. He is currently hiding in the corner of my bedroom right now even though the kitten is in another room.
I know people say it can take months but it's really distressing seeing my cat like this and knowing I caused it by bringing an intruder into his home. He wasn't aggressive to her at first. Her scent didn't bother him, then when he saw her behind baby gate he hissed a little, but seemed to be coping ok. But now he has gone backwards and suddenly got worse. Growling at her very loudly with ears back etc. Poor little girl just wants to play with him.
Even though people say it can take weeks or months, I just don't know if his personality type is ever going to accept her and not be scared of her. I don't know whether to stick it out and keep trying or get the hard part over with and give her back now while she is still young (10 weeks) enough to find a new home quickly.
I am honestly in tears imagining her not here anymore. The funny little things she does, her little squeaks, seeing her zoom around the house (while cat is out), falling asleep on my shoulder. I love her so much and the thought of dropping her back with the breeder and coming home to a house without her is breaking mt heart. But I know that it's selfish and I can't let my boy suffer.
I just needed to get it out anyway and get it off my chest and see if anyone has any wise or comforting words
