Feline advice needed

[Miaou]

Dh and I are the proud owners of a LARGE 9 yr old tom (Kerry). He is lovely but v. terratorial.

My mum and dad are giving us their cat (Cassie), an equally LARGE (although more fat than muscle!!) tom who must be about 12 years old.

We have happily agreed to take him on (he was my cat before I left home!), but I'm wondering what to do re. settling Cassie in and not upsetting Kerry too much. Both cats are neutered and we are surrounded by countryside so they have plenty of places to go outside - it's more the indoors ettiquette I'm worried about!

Any suggestions gratefully received!

Take it very very very slowly!!!
Put Cassie in a spare room, with toys bed etc and give her a few days to settle in. Obviously try to spend time with both cats. Then take something from Cassies room and put it near Kerry so that she can smell her. And the same for something of Kerrys. After a couple more days try getting them to meet. Take cassie out of her room, as this will have become her haven, and see how it goes. They may hiss at each other but just let them know the other exists. Just for a few minutes. You will have to repeat this a lot and then gradually increase the time they spend together.
They may get, or they may not. There is no way of knowing!
You could always phone your local cats protection branch for advice, or they may have some info on their website.
Good luck

I had 2 siamese boy kittens who were inseparable. At the age of 4yrs, Toby (such an amazing cat) died of a heart defect and three months later I then got a kitten for companionship for his brother. Big step this.

I was told to keep the kitten separate in another room and to give him a toy of the resident cat on day 1, and then to introduce something from the kitten to the resident cat as a first introduction. When they met on day 2, it was supervised and the resident cat just kept away and paced angrily while yeowling.
The next day (day 3), I got a cloth and stroked each cat a few times with the cloth to exchange scents about 5 times that day. At 4pm on the same day I then got out a fishing rod toy and played with both of them. Because their instinct to chase is so strong, they forget themselves and both join in. This worked and the ice was broken.
I was given this advice by an animal behaviourist, in case you were wondering. Good luck!!
