Can A Mother Cat Be Safely Introduced To Another Female And Male?

[mattkat]

We have a mother cat (named Gracie) who had kittens 9 1/2 weeks ago, and she will be spayed soon. The kittens will be adopted soon. We already have two cats, a male and a female, and we were wondering if Gracie can be safely introduced to our two cats. She is a very sweet cat, and we want to take her in, but we don't know how our cats will take it.
Our male cat (Tiger) (~9yrs.) is friendly towards ceratin cats (around the neighborhood), however he is not so happy towards other cats, such as our female cat, Whiskers.
Whiskers (~7yrs.) gets along pretty well with Tiger, but with neighborhood cats not so much. She is anti-social towards other cats sometimes.
Gracie and our cats might not get along, but I've heard there are ways to properly introduce cats.

You'll likely be able to introduce her as long as you take it slow, but I would hold off until the kittens are gone. As long as she has them, she'll be in protective-mom mode and will likely be stand-offish to your cats. Once the kitens are out and she's spayed would be the best time.
A good place to start is with this article:
How To Successfully Introduce Cats: The Ultimate Guide

It gives some great tips on helping your resident cats get along with a newcomer.

Where is Gracie now? In a room in your home?

Some male cats will kill and eat kittens who are not their offspring. I wouldn't let the male near the kittens for this reason.

Actually Gracie and the kittens are in another house that we are flipping, and they aren't near our other cats. We're keeping them at the house until the kittens are gone, but we need to sell the house soon, and we might want to take Gracie in to our house after she's spayed and all.

She should be fine once she is spayed and adjusted. You'll need to do a slow introduction at the pace that's comfortable for all of them.

Are mom and kittens totally secured in the house?

Thank you for helping them!

Thanks.

Yes, they are.
