Don't expect them to get along straight away. Imagine it's you and a new person comes to live with you, a total stranger, it would take you some time to get to know the new comer.

Remeber your Tom may feel jealous. Be sure to get him alone in a room and give him lots of love and praise etc.

You should have introduced the kitten more slowely. Leaving her have one room then swapping blankets and beds between both cats to swap scents etc.

Cover both cats in talc, they will smell the same and it may help. Play with the together with a dangly toy or something.

When your tom is being good praise him, give him a treat etc. Though as I say it's early days and he's used to being alone.

I could take a couple of weeks or more but so long as it's just hissing and he's not attacking then that's good. The hissing will lessen and I'm sure he'll enjoy having some one to play with and run about with soon enough.


Try not to frett too much either, the cats pick up on this and makes them stress too. Also, maybe try a feliway plug in, it contains feline scent which helps calm and ease cats.
