My cats keep bullying a specific cat
I have 5 cats they are all siblings and I had them since their birth. One of them was just born terrified and scared. She never went through anything to make her that way I promise. She freaks out when she sees me and run away and hide etc. 2 years forward, I had to separate her from her siblings for a medical reason for about 5 days. I’ve done that before to all of them and they tend to hiss at the separated cat for few hours then everything goes back to normal. Well not this time. They never accepted her back. It’s been a year since. They attack her all the time and hit her. They don’t hiss at her and don’t look like they’re scared of her. She’s the one who hisses and cries. Its like if they like the reaction they get from her. I don’t know why all of them keep doing that. They fight with each other occasionally but not this way. They target her all the time. It’s been a year and I don’t even know what to do.
