Just over a month ago a small female cat appeared in my house. One night I was sat in my room and she came wondering in, had a look around then jumped up onto my lap and that was that. I tried to find out where she'd come from with no luck, and at first I did try and kick her out but she'd just come straight back in (I always had a small window open for my own cat to come in & out). I don't know if she was a stray, she was a little skinny & would go absolutely mental when I was feeding my cat, scratching and biting to get to the food if I moved her away, but she wasn't overly scruffy looking.
Then 2 weeks ago my lovely ginger boy was hit by a car and killed. The kids were devastated, I was (and still am) heartbroken, and this little girl just seemed to fill the gap he left. I'm probably wrong for doing it but I've been feeding her and I've stopped kicking her out and now she's here almost all of the time, and we're really starting to love her. And it has become increasingly obvious that she's pregnant.
I'm happy to keep her here, and look after her & her babies until they're ready to leave her, but I have no idea how to care for her. Should I take her to the vets? What should I look out for? Her stomach is growing rapidly, she's very round now and her nipples are swollen. I can also see and feel the kittens moving around. She was sick in the night last night - is this something to worry about? I've done some reading online about pregnant cats but was wondering if anybody who's experienced it themselves could give me some advice? She looks quite young too, which is worrying me.
Thanks.
