Care of Your Pregnant Cat
Due Date
To calculate the due date of your cat, count 65 days from the FIRST date the two cats were bred. It is not unusual for a cat to go as long as 70 days from the FIRST date of breeding. Many breeders will breed their queen for 1-4 days. I usually do not go past four days because kittens could be born on the first day of breeding as well as the later days and those younger kittens might not survive.

Confinement
Litter
Whatever you do, do not allow your cat to have clumping or clay litter. If she decides to have her kittens in the litterbox, the kittens will be a mess and it will be very difficult to get them cleaned up. I use the Tidy Cats Breeze Litterbox system. This litterbox uses pellets which are safe for kittens.
If you use clumping litter and do not want to switch, then as soon as a “bubble” appears on your queen then either remove or cover the litterbox to prevent her from having her kittens in it.
Birthing Box
I use a pet kennel without the lock/nuts on them, so the top just lifts off to allow you to check on the queen and the kittens. I put a folded towel draped over the top to provide privacy for the cat and put another towel or pee-pee pad on the bottom of the carrier for the cat to birth on. I prefer a pet carrier that has a top creating a “den” for the cat. Afterall, in the wild they would be giving birth in a small hole. I also like using towels better than a pee-pee pad for the queen to birth on as they absorb the birthing fluids better. At least, I think so.

Some breeders like to use an over-sized UNUSED litterbox as a birthing box.
Diet
Medications
Ultra-Sounds or X-Rays
I do not take my queens to the vet for ultra-sound or x-ray as I do not want to expose them to possible germs, etc. at the veterinarians. UNLESS I suspect there may be an issue with the mom.
Some breeders do take their queens into the vet to get these tests so they know the size of the litter, size of kittens, etc.
Veterinarian
Make sure you have an established relationship with a veterinarian prior to your cat’s queening date in case of emergency or a c-section.
