How we calculate this
Cat pregnancies last about 63 to 65 days. We add these to your mating date and show the middle of that range as the due date.
A scan before day 21 can miss a pregnancy, so if an early scan is negative your vet may check again later.
Questions people ask
How long are cats pregnant for?
About 63 to 65 days, which is roughly nine weeks.
When can a vet confirm my cat is pregnant?
A vet may be able to feel kittens from around day 21. An ultrasound scan can confirm pregnancy from about day 25, and works best between days 25 and 35.
When should I call the vet?
If she seems unwell, strains for a long time without a kitten arriving, or goes well past her due dates. If you are worried at any point, call your vet.
