What to do?

A cat we have previously owned for a year has become pregnant. We have no idea what cat made her pregnant, however there are stray cats that can get into our yard. Since finding out, we have kept her indoors and away from our other animals, set up a litter box and whelping box, and fed and watered her constantly. Anything else we can do for her? We are planning on having her spayed after the birth of the kittens, and when they are old enough, the kittens as well.

Can anyone help?

feed her kitten food. how far along is she?

That's the problem. We have no idea when she became pregnant. But we can see the kittens moving.

Cat Pregnancy

Sneaky ones aren't they?   Anyways when was the last time she was in heat? If you know you might be able to roughly guess.

It was about one and a half months ago, about the end of March

Then  she is possibly 5 to 6 weeks along, roughly half done. I do know that after about 21 days after mating, the nipples will turn pink. Here is a rough date on cat pregnancy calendar.   http://www.cat-pregnancy-report.com/cat-pregnancy-calendar.html

I used this on several strays, pretty accurate.

Thanks!

Her nipples are very pink, almost a reddish color

Is she especially large or rounded belly? If so, she may well be nearing delivery time.

She is huge. She also has white crust on and around her nipples.

Sounds like she is near, but it could still be end of May or early June since you said her heat was around the end of March.

Good luck!

Thank you!

The kittens have arrived! I was at work, and when I got home, the kittens were born! Momma was under the bed before I left, so I should have thought about that!

Oh my! Sooner than I thought! They look so healthy! Mom did a nice job! Congratulations to you!

Thanks! The kittens seem to be doing fine.

wow, cute little ones, glad for an uneventful delivery. All are looking well.

How many, six?  That will keep her busy...you too.  They are adorable.  Glad everything is going well.  Keep us updated.

Everything is going well, mom is leaving more often to eat, drink and use the litter box. Yes, there are six kittens. 4 males and two females. However, the two orange males still have their umbilical cords... They are dried up but have not fallen off yet.
