I think your main priority is to get the cat to the vet and see what is happening, hopefully she will be ok, she is indeed a very beautiful cat.

I am very happy to hear that you have found homes for all the kittens, that is warming news, and that you will have her spayed after she gives birth, that is the responsible thing to do, and she is lucky to have been found and cared for by you.

I think everyone was just concerned for her welfare, I myself had the same questions which you have answered honestly, thank you for that and putting many people's mind at ease.

Please keep us posted and fingers and paws crossed here that everything will be alright with your cat.
