How do I stop older cat from chasing younger one?
I have two 2 year olds and a 1 year old male. A few months ago, I brought my 10 year old female down and introduced them slowly. Now the older female is chasing my 1 year old male out of the house or up the stairs and down.
I think she’s very territorial of the living room. But she just did it again from my son's bedroom to the kitchen window where they come in and out. What do I do? Any help appreciated. x
