My month-old kitten's anus looks swollen. Is it normal or serious?

Luckily it looks like her anus is just swollen and red causing it to protrude. I don't see any sign of a prolapse thankfully. Try and keep it clean and comfortable until you can get to the vet tomorrow.

There is nothing I would be worried about as the anus seems only mildly inflamed. Usually this is caused by softer feces/diarrhoea. I would recommend to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, vomiting, lethargy or inappetence. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. Please find the time to give us a feedback about the consultation as that will be used to improve our service.

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.

Swelling of the anus/rectum could be due to constipation/hard stools, anal gland issues, allergies, irritation, or other problems. You would need to have the area looked at by your vet to determine what is going on and get the appropriate treatment. Be sure to let your vet known of any other issues you may have seen such as changes in appetite, energy levels, stool habits, etc. You can also use an Elizabethan (cone) collar to prevent your cat from licking/chewing at the affected area if it is bothersome until you can get to your vet.

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. While his anus does appear a bit swollen, it is not alarming. Jasper probably needs to be dewormed, as this is a very common problem in young cats & kittens. Once dewormed, the swelling & bowel movements should normalize. Take care.

He may be constipated or have a partial rectal prolapse. Veterinary attention is recommended to diagnose the underlying cause prior to treatment. Submit a stool sample to diagnose intestinal parasites which are a common cause of the symptoms described, especially in kittens.

If your pets anal area is swollen and there was diarrhea before this happened, then there are two possible scenarios here 1) Your pet has severe colitis and needs antibiotics (Metronidazole helps with GI issues and inflammation of the gut) prescribed by a veterinarian. They will also recommend a bland diet of boiled chicken and rice or cottage cheese or a low fat dog formula like Hill's I/D or over the counter Purina EN Gastrointestinal and potential probiotics (you can try Culturelle it works great). 2) If the swelling is actually to the side of the anus then this could be an impacted anal gland- which also should be treated and express by a veterinarian.
