Just took in a pregnant cat

Hi everyone I'm new to the forum. I have looked through some threads and all the advices are really helpful.
So yesterday I took in a pregnant cat, my friends Frd can't keep her anymore. They told me she is under one years old. I don't know how long has she been pregnant, but today she let me pet her and her nipples are really hard and they are pink.
I have another cat myself, she is 7 months old. I separated them but just now when I was cleaning up I forgot to close the door between my bedroom and my living room. They saw each other and they became very cautious and they stared at each other and raised their tails. I separated them right away.
Now that when I'm inside my bedroom with my cat, the pregnant cat meows outside really loudly and scratches the floor. When I'm in the living room with the pregnant cat, my cat meows and scratches the door.
I don't know what should I do because I don't think they will be nice to each other.
What should I do? Did anyone have similar experiences?

As they both seems to wish to learn know each other, you can do it, let them meet again with your supervision,  Talk softly and sweetly to both...   Be also sure both know  the meeting room and are OK with it, and there are places to fly into in that meeting room.  You can have open doors from this room to other rooms.  And or a couple of shelters to jump up to.  Or hide under.

Be sure your resident knows you love her the resident, so she doesnt feel any need to be jealous nor has any need to chase away the "usurpator".

Them becoming cautious, staring and raising tails is quite normal, and it doesnt shows any especial aggressivity nor hostility.   Im sure they can become friends quite easy, even without any elaborated measures.

Otherwise, in our Behaviour Forum there are lotsa of threads how to let them meet and become friends or at least, accept each other, even if they were hostile in the beginning. "introducing"

Normally, with a fostered high preg, it is not necessary to let her come into contact with the residents,  You will kept her isolated anyway.  You dont want to stress her in any way.

But as they did discovered each other, arent openly hostile, and decisively seems to want to meet each other - it may be better they do meet.   Wanting to meet, but not being able to, is stressing it too...

With a little luck, they will become best friends.  In that case, your resident will perhaps even become her help mother.

Re how long she is.  It is not easy, unless you know exactly when they mated.  (tip: they sometimes get sore in the neck, as the male bites them in backwards in the neck . if she come home with a sore neck several weeks ago - this was that occasion - just to count on fingers...   65 days after).

If you arent very experienced, the best station is when you begin to feel the kittens move. It is usually about 2 weeks before the expected delivery.

Good luck!

And some links about how to find a cheap spaying place if you live in the USA.  The same places may probably also help with a more cheap vet treatments than the average fashionable full payment vet clinic:

cheap  spaying:
If you are in the U.S. ,  the ASPCA has an online database.  http://www.aspca.org/pet-care/spayneuter

I don't know if pregnancy has an impact here, but I'd assume this is about cat introductions.

Basically, your rule of thumb is to keep new cat and resident cat separated from each other until both cats are displaying only curiousity - no fear, no aggression.  It sounds like they are already curious and wanting to meet, but I don't know all that is going on, so you will have to make the call on whether there is any fear or aggression left.  

When they are ready, have a controlled meet.  Be prepared with a towel if you have to intervene should things get bad (they won't if you have waited until only curiousity is there), and also some toys as these can diffuse any moment that gets a bit intense.  Leave the door open, so they have an avenue out if they need it.  And plan to keep the meeting short.  If it is going really well, you can give it more time.

Steps to take while you are 'waiting' from them to reach the 'just curious' stage before meeting include scent swapping (rub a cloth along cheeks, and present that cloth to the other cat with happy noises and treats - then do the same thing for the other cat), site swapping (switch rooms so new cat gets to explore more of her new home, and when she goes back to her special room, her scent will be in the other part of your house for resident cat to get used to), feeding treats or meals close to the door of new cats room (good things associated with new cat smell - and they won't eat in close proximity to that door until they are feeling ok with each other, so it is a good yardstick; you can slowly move their bowls closer and closer to the door over time).

Best wishes, and thank you for taking in this young mum-cat.  If only people did the de-sex thing in time!

thanks so much @tammyp  @StefanZ  . i decided to separate them until the mama give birth to the kittens. i dont want to stress her out.

The pregant cat is not eating alot, i gave her a can of wet food this morning and it is 6 pm already she barely ate half. Is this a sign?

It may be, if the delivery is very near.

But it may be a lot of other things too.  Including she isnt fond of this brand...

The problem is, it may also mean she isnt well.    So have your eyes open!   How is her temp?   You can measure in her fore arm pit.  Its just a little lower there.

You live in USA?   Baby food Gerber stage one, or even stage two, they say is irristesible.  For finicky cats, and for small kittens to begin to eat.     The flavors of chicken or turkey are best.

A stray "should" ate anything, they dont afford to be picky.  But I had heard about finicky ones....

dont let out wet food lay out 12 hours.    Better to give a small portion, and have the rest somewhere cool, waiting.

Good luck!

@stefanz I don't have a thermometer with me at home... And she is a bit scared of me we have only been together for 4 days ... She s okay with me petting, but I don't think she will allow me to lift her up. I will get a thermometer tmrw and try to measure her temperature.

Another thing, starting last night she has been staying inside her litterbox. Today she was sleeping there. She only went to the box I prepared for her when I was changing the litter. Is she gonna give birth inside her litter box? I am so scared! I am using clumping litter..... I tried to lure her out by giving some treats, but as soon as she got the treat she took it back and eat it inside her litter box?

Just now I was petting her I paid extra attention to her tummy I felt something was moving inside.

She has been eating less than my 7 month old cat (koko) . The first day here she could finish a whole can and some dry food but now she can only eat half. I m feeding both of them wellness kitten food.

I think I should just leave her alone now, but I really don't want her to give birth in the litter box. What should I do?

Get rid of that clumping litter because if one of the kittens ingest it, it could block in their intestines. Only use nonclumping with kittens.
