My kitten has diarrhea, swollen belly, and acts like she's in heat.

Poor Beebo! It could be that she is suffering from roundworms again if she's had them in the past, but a pyometra could also be a possibility. Other signs of a pyometra in cats can include vomiting, lethargy, and a discharge from the vulva. If you are really scared she has a pyometra, my advice would be to bring her into a vet right away. A pyometra is fatal without treatment, and time is of the essence for the success of treating them. In my opinion, it's always best to be safe than sorry, and I'd rather have an animal checked out with nothing wrong than not have them checked out and it be something serious. If it would set your mind at ease to have Beebo seen by a vet, I recommend taking her into an ER vet now. Best of luck, I hope this helps!

Oreo cannot be pregnant and still be in heat. False pregnancy is rare in cats: https://www.merckvetmanual.com/cat-owners/reproductive-disorders-of-cats/reproductive-disorders-of-female-cats A swollen belly could indicate many things including parasites or FIP. I recommend to have Oreo examined by the veterinarian today. It's better to play it safe. Also, I recommend to have Oreo spayed. It has many health and behavioral benefits. It will also help to combat the extreme problem or pet over population. https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-cats/ I hope this helps.

My biggest immediate concern would be for intestinal parasites. Most kittens have them, and if she hasn't seen a vet yet and been dewormed, she needs to. She's suffering pretty significant fluid losses for a tiny creature. Make an appointment tomorrow, and bring a stool sample with you, so that the type of parasite can be determined and appropriate treatment started.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Even though you do not seen worms, it is possible that Cupcake still has gastrointestinal parasites causing her diarrhea with blood. GI parasites are one of the most common causes of diarrhea in kittens, and are easily treatable with deworming medication from your veterinarian. Other possibilities include viral infections and/or dietary indiscretion (eating something she shouldn't have). Regardless, I recommend having her evaluated by your veterinarian so he/she can perform an analysis of her feces to determine if and what parasites are present, and prescribe the appropriate treatment. I do NOT recommend purchasing products from either a pet store or food store, as these medications are not regulated and/or proven to be safe and effective for use especially in young kittens. I hope this is helpful!

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.

She likely has a viral infection that is causing all the discharge. You can use a warm wet washcloth the help her stay clean, and a round of prescription antibiotics and eye ointment may be needed. Her large belly is probably due to intestinal parasites, though there are a few congenital causes that may be at play. I will warn you, that sometimes these kittens will lose an eye from the infection, and will likely have chronic infections over their lives.

Hi and thank you for using Petco Pet Education Center, formerly Petcoach. I recommend taking Lea to the veterinarian as diarrhea in a kitten this young can quickly become life threatening. She may have parasites that need to be treated. Good luck, I hope she's better soon.
