Cat only had one kitten
It is important to take your cat to the vet, as it has to have more kittens that is taking too long to expel, or possibly dead foetuses.
You should take your cat to your veterinarian as soon as possible so there they can examine her and take the necessary steps to remove the remaining foetuses / kittens that have not been expelled yet.
In the meantime, it is very important to keep the born kitten warm and hydrated, and make sure the baby nurse. If not, you should start feeding him with freeze-dried milk. There are specific powder milk for kittens you can find in pet shops.
All the best for you and Carly.
