I'm sorry I really would like some advice. I don't know if anyone can help? I have a 2 year old cat from a rescue home and just got a new kitten. My old cat is so miserable about it that even though the kitten is shut in one room most of the time (vet's advice) she will barely come in the house now.
I'm so sad I got the kitten for my son's birthday and may have to get rid of him again even though my son adores him.
My older cat now hardly comes in the house. I have just shut the catflap with both of them in the house in the hope that they sort it out eventually.
