Taking in an indoor cat

[SilveryMoon]

We currently have a male indoor cat (used to have 2 but the other one died), 3 yrs old.
A friend of dp's wants to re-home his female indoor cat (both cats been done) as his ds is pulling and kicking her. This cat is also 3 yrs old.
Dp said we will take her as a friend for our cat, I do think he needs a friend.
How would I best go about introducing her to our home, family and getting both cats used to each other?
Is it likely she'll need her own litter tray and food bowls, or is there any hope that they'd share? I'm thinking not and I'll need 2 of everything (which isn't a problem)
Any tips on how to make the transition as easy as possible for both animals, would be greatly appreciated.
TIA

Yes, the new cat will need its own food bowls and litter tray. (The general rule is one litter tray per cat, plus one spare, but you might be able to get away without the spare). Over time, as they make friends with each other, they might start to share the same litter tray in which case you'll be able to go down to one, but you'll have to see how it goes.

It's best to introduce cats to each other very slowly. If possible, put the new cat in a room on its own to begin with, and then take something that smells of new cat to the old cat, and vice versa, so that they become familiar with each others smell. If they don't respond badly to this, you can move them closer - but take it slowly. It will help to transfer scent between the two cats - rub a cloth on their cheeks where the scent glands are, and then rub it on the other cat. This will make them smell similar.

Give the new cat time. Depending on the cat, it might be out and about straight away, or hide under the bed for a few days. Don't rush it. And make sure the old cat still gets lots of attention from you, as usual. Good luck!
