Pet Gestation Chart

Household pets have short pregnancies. A dog is pregnant for about 63 days, a cat for about 64 days and a rabbit for about 31 days. Because the whole pregnancy lasts weeks rather than months, a few days of uncertainty matters, so confirm the mating date and prepare the nesting area early.

What these animals have in common

Pet species give birth to litters of small, helpless young that are born blind, deaf and unable to regulate their own temperature. That pattern is the reverse of livestock: development is finished in the nest rather than in the uterus, so gestation is short and the demanding period is nursing rather than pregnancy. Owners usually know a mating date only approximately, which is the single largest source of error in a pet due date. Progesterone testing in dogs narrows the window from about a week to roughly two days, and an ultrasound from around day 25 confirms the pregnancy and rough numbers. Litter size matters too: a large litter typically arrives a day or two early, while a single puppy or kitten may run late and sometimes needs veterinary help. Prepare a quiet whelping or queening box a full week before the earliest date, keep the routine unchanged, and know the signs that labour is not progressing.

Frequently asked questions

How long are dogs and cats pregnant?

Dogs average 63 days from ovulation and cats about 64 days from mating. Both have a normal range of roughly a week either side when the mating date is uncertain.

Which pet has the shortest pregnancy?

The rabbit at about 31 days, which is why unplanned litters happen so quickly when a male and female share a hutch.

When can a vet confirm pregnancy in a pet?

Ultrasound detects a canine or feline pregnancy from about day 25, and an x-ray from around day 45 gives a reliable count of the young.

What should I prepare before the due date?

Set up a quiet, warm nesting box a week before the earliest date, keep feeding and routine consistent, and have your vet's out-of-hours number to hand.
