Brief background for those who don’t know us! Always been aggressive with us as she was not socialised as a small kitten, she is now a 5 year old tabby cat Popcorn. History of ill health but doing well atm! Now unable to be handled by us and vets without a general anaesthetic and even then it takes 3 people and a crush cage to treat her. Luckily she hasn’t been ill for ages as it’s so stressful for her. She has a furless 2.5 year old brother who absolutely adores her and worships the ground she walks on. He loves her more than us!! Now here’s the issue! She has started attacking him. He has never ever been rough with her or hurt her. He is THE most gentle soul put on the planet and loves all animals spiders included. From day 1 he has been taught how to deal with her - given her space, head bumps when she demands them, feeds her treats - she goes to him meowing for food half the time! Suddenly this week she has run at him twice and swiped him scratching his back on both occasions as he’s had his back to her once reading a book and secondly just standing whilst I talked to him, this has happened in the bedroom whilst he’s been on the floor and she’s been on the bed - where she wants to be!! Any ideas or advice please folk because I don’t want him keep being scratched and he’s now avoiding her and cries when she walks near him!
