At What Age Can a Cat Become Pregnant?

Cats can enter their first heat between four and twelve months old. They can get pregnant the very first time they mate.

Signs Your Cat is Pregnant

  • Pinking: About three weeks after mating, your cat’s nipples will become pinker and larger.
  • Behavioral Changes: Your cat may become more affectionate.
  • Increased Appetite: Expect her to eat more.
  • Nesting Behavior: She might search for quiet places to give birth, like closets or cupboards.
  • Vet Confirmation: Pregnancy can be confirmed by an ultrasound from around day 22.

How Long is a Cat Pregnant?

Cat pregnancies last between 60-67 days, and most cats deliver kittens in about 63 days. If it helps, think of it as nine weeks—similar to nine months for humans.

Gaining Weight

After about four weeks, your cat will start gaining weight. Her tummy will begin to swell noticeably.

Signs Your Cat is Going Into Labor

  • Mammary glands increase in size, and milk production begins about two days before birth.
  • Your cat's temperature may drop to 99°F, and she might eat less.
  • Nesting increases; she might follow you or become restless.
  • Additional signs include purring, meowing, panting, licking genitals, or vomiting.
  • You might notice vaginal discharge and contractions as labor begins.

Once these signs manifest, the birthing process will soon follow.
