Oh how exciting! If you introduce the new kitty by keeping her in a spare room for a week or so, allowing Marigold to get used to the new smeel of a new cat. Perhaps putting a blanket in the room for the new kitty to sleep on and then giving it to Marigold to smell.

You can never tell how a cat will react to another cat. I always was afraid Allen wouldn;t take to Pouncer, but it was a match made in heaven, Then when I started to foster cats, I was SURE Pouncer would LOVE the kittens to play with -- he doesn't. He spits and growls. I have to be careful and only take an occasional foster in now because he doesn't handle the stress well. He was not happy about Abby and Harry at first, but now he loves his little siblings.
