Why is my young indoor cat's belly bulging like she's pregnant?

I see that Princess isn't spayed. I would be concerned that her accidents in the home and her distended belly is due to a pyometra. This is a life threatening infection of the uterus that causes it to become enlarged with pus. I would have Princess seen by a vet immediately. My recommendation would be to have a physical exam, blood tests, a urinalysis, and possibly x-rays to diagnose if she does have a pyometra. If she does, the recommended treatment is spaying her. Please take her into a vet now.

Yuki's nipples and mammary glands look like those of a pregnant cat. I see that she has not been spayed, so if she got out of the house or has been around ANY intact male cats, I think it's most likely that she's pregnant. If there is absolutely no chance that she's been around any intact male cats, then there is a chance that her body is going through a pseudopregnancy. These false pregnancies can occur due to hormonal imbalances after being in heat and usually last a little over a month. It would be best to have Yuki examined by her vet to determine if she is or is not actually pregnant in order to help you plan for her care. I hope that everything goes well!

If she has been swollen around her bladder, then this could just be an actually problem like a hernia or something benign like a fat pad. Since she is vomiting and then swelling has been there for awhile now, I would have her checked out at least once to ensure it looks okay. Your vet will be able to tell you whether it is anything to worry with or just to continue to watch. The vomiting could be a complication of a hernia or a different problem like hairballs, eating food too fast, an infection, etc. I hope this helps!

I am sorry to hear about Paris! In an unpsayed female we do worry about pregnancy as a possible cause of abdominal enlargement. This can sometimes change a pet's behavior and make them more vocal. Other possibilities could include weight gain, fluid in the abdomen, enlargement of an organ in the abdomen, or a tumor. Hair loss/excessive cleaning can be caused by a variety of issues as well, often due to an allergy (to fleas, environmental allergens, foods) or can be behavioral. I would recommend having Paris examined by a veterinarian to try to determine the cause of these issues.

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! It is hard to say what the cause of the rounded abdomen may be without examining Binx first. If she is not spayed and has interacted with a male cat, she may be pregnant. Other options include a parasitic infection, mass or tumor, or abdominal fluid due to Feline Infectious Peritonitis or another cause. A good exam with Binx's veterinarian is needed soon in order to determine the cause of the rounded abdomen. It is good to hear she appears normal otherwise, but I would take her in to see her vet to have her evaluated.

This could be a pyometra. A pyometra is an infection of the uterus that is fatal without treatment. With a pyometra, the uterus fills with pus, and that can cause the belly to get big. Have Peekaboo seen by a vet now.

"Mama" is a very pretty girl! :) I agree that her abdomen definitely looks enlarged. It's possible that she could be pregnant, but the enlarged belly could also be caused by something else such as an abdominal tumor, heart or liver disease, or FIP (feline infectious peritonitis). Cats are only pregnant for 64 days on average, so if her belly has been swollen like this for more than a few weeks or so, I would be very concerned that something else is wrong. The best way to find out would be to take her to the vet for an exam - he/she can palpate her abdomen and may also recommend x-rays or ultrasound to help determine for sure what's going on.
