Pregnant cat nipples become noticeably larger, rounder, and turn a distinct pink or reddish color (called "pinking up") around three weeks into pregnancy, a sign of increased blood flow and preparation for nursing, often becoming more prominent as fur around them thins, making them easier to see compared to their normal small, pale state.
The first thing you'll probably notice are her nipples. Cats' nipples become red and engorged when they become pregnant. This is called “pinking.” This usually occurs two or so weeks after she gets impregnated. The other big change will be her belly.
Early Changes: The Pinkening of Nipples The initial sign of pregnancy surfaces around two to three weeks after conception. Your cat's nipples may start to swell and take on a deeper pink hue. This transformation, often referred to as 'pinking up', may be more noticeable in cats with lighter fur or skin.
The primordial pouch will feel soft and empty, while a pregnancy will feel more solid because there are fetuses in there.
Since cats show early, if you look at a pregnant cat from the side you will see a bulging abdomen. Avoid touching the belly as you may hurt the mother or the unborn kittens. Overweight cats usually gain weight all over and not just the abdomen.
Physical Changes:
One of the earliest signs of pregnancy in cats is the enlargement and pinkening of the nipples, often referred to as "pinking up." This is usually noticeable around the third week of pregnancy. Pregnant cats tend to gain weight gradually as the pregnancy progresses.
Behavioral Changes
Many pregnant cats become more affectionate or seek out secluded spaces as they prepare for the kittens. This nesting behavior is typical as they instinctively begin creating a safe, comfortable area for giving birth.
In non-pregnant cats, their nipples are typically small and firm, not easily noticeable unless deliberately looked for. Sometimes, a small bare skin area may be visible around each nipple. Still, the only visible part often is the small nipple itself, which may resemble a wart.
How To Tell How Far Along Your Cat Is
Although pregnancy hormones temporarily block full milk production, areola changes become more noticeable. Your areola (the area around your nipple) darkens, and your nipples might leak a little fluid. Don't worry—this is colostrum, the first milk your body produces to nourish your baby.
During week four, you'll notice your cat gaining weight and your vet will be able to confirm her pregnancy with an ultrasound. You should avoid picking your cat up at this stage so you don't accidentally harm her or her growing kittens. Speak to your vet about the proper way to handle a pregnant cat.
The typical cat gestation period can last 62-65 days. Your cat often won't show any physical symptoms of pregnancy until they are a few weeks into their term. If you think your cat is pregnant, take them to the veterinarian for confirmation.
Top 10 Ways to Tell If a Stray Cat Is Pregnant
If a female cat is pregnant her nipples will usually start to become enlarged around week three of her pregnancy. This is when the mammary glands below swell with milk. They will continue to swell until the kittens are born.
Enlarged nipples: A pregnant cat's nipples will be enlarged in preparation for the babies. While nursing, a cat's nipples will already be slightly larger than usual. Yet, if they continue to enlarge even after the kittens have started to wean, this could be an indication of a new pregnancy.
New Cat? Set Realistic Expectations! You can expect that it will take your cat some time to get used to the new routines and environment. The 'Rule of Three' means that you can gauge the time it might take for your cat to fully acclimate to his home in threes: three days, three weeks, and three months.
Note that a pregnant cat will gain weight mainly around the belly. If you look at your cat from above, you will see that from the neck to the tail, she has something of a pear shape. A fat cat is a little bulkier everywhere, including in the neck and around the legs.
Nipples. A few weeks into pregnancy, your cat's nipples may swell and turn a pink colour – which is an indication of pregnancy. During the last week or so of pregnancy, you may notice your cat starts to produce milk.
Although there might not be any signs in the first weeks, there are some common early pregnancy symptoms that can appear:
While your cat might become territorial over her space and toward other animals in the house, she may become more affectionate toward you. Due to hormonal and neurological changes during pregnancy, you may notice your furry friend is seeking your attention more often than usual.
Maternal behaviours: Pregnant queens often display maternal behaviours — they purr more and demand more attention from you. Positive ultrasound: Some vets offer ultrasound exams. If you see kittens on the screen, your cat is pregnant.
After mating the female will seem very agitated and will roll and thrash around. This is normal behaviour. The whole mating process can take between 30 seconds to 4 minutes. A female can mate up to 30 times during one estrous cycle.
Cat pregnancy lasts about two months, so once they become pregnant after their heat cycle, unless you see those subtle signs, they'll start showing their pregnancy in the last few weeks. Around six to seven weeks from when their heat cycle ended, you would start to see the belly growing.
