To know if a cat is pregnant, look for these key signs and changes, which typically develop over the course of her approximately nine-week (63–65 days) pregnancy: Early Signs (around 2-3 weeks into pregnancy):
- Nipple changes: The nipples become pinker and more prominent, a phenomenon called "pinking up"
- Behavioral changes: The cat may become more affectionate, calmer, or more docile than usual
- Cessation of heat cycles: If your cat stops going into heat, this may be an early indicator of pregnancy
Mid to Late Pregnancy Signs (around 4-6 weeks and onward):
- Enlarged and swollen belly: The abdomen starts to visibly swell as kittens grow, noticeable around 4-5 weeks
- Weight gain: Pregnant cats typically gain 2 to 4 pounds over the pregnancy period
- Increased appetite: Appetite may initially decrease slightly but then increase significantly as pregnancy progresses
- Increased grooming of the belly and nesting behavior: The cat may lick her belly frequently and seek out quiet, hidden places to prepare for birth
- Vomiting or "morning sickness": Some cats may vomit due to hormonal changes, though this is not a definitive sign
Confirming Pregnancy:
- A veterinarian can palpate the abdomen to feel fetuses about 2.5 weeks into pregnancy.
- Ultrasound can detect kitten heartbeats at 3-4 weeks.
- X-rays can show kittens’ skeletons around 6 weeks
If you suspect your cat is pregnant, a vet visit is recommended to confirm and to ensure proper care throughout her pregnancy. In summary, look for nipple color changes, cessation of heat cycles, weight gain, a growing belly, behavioral shifts, and nesting behaviors to identify pregnancy in a cat
