Why is my 6-week-old kitten's bottom swollen with loose stools?

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.

It will go down one the stools become normal, i suspect at the moment he is suffering from diarrhea and this is why the anus looks like that, once the stools become normal again the anus will recover.

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.

Because Sombra hasn't had wet food before, it could be this causing her red and swollen anus. But it could also be due to something else like intestinal worms. Based on the picture, I think having her seen by a vet before you leave is the best idea. You don't want it to get worse while you are gone, so having her seen before you leave will give you peace of mind on your trip. Call the vet today to make an appointment. Best of luck, I hope this helps.

Hi there. Smokey likely needs a fecal exam at your local veterinarian to test for intestinal parasites. This is very common in small kittens-but upon presenting with a prolapsed anus it becomes more serious. Best to be seen as soon as possible. Hope this helps!

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.

Poor girl. So it seems that Lela has a moderate amount of colon inflammation and a little bit of the colon is actually prolapsed (pushing outward). She should be seen by your vet immediately to have this area evaluated in person and determine if she needs to have this surgically repaired. I hope that you get some resolve soon for Lela and I am hoping for a full and speedy recovery. It is amazing what cats can go through and not seem to be affected by. They are truly the masters at hiding discomfort and pain. But we have to not use that as a ticket to avoiding proper veterinary care. The vet may even want to prescribe an anti-inflammatory medication to see if they can get this to reduce in size. Best wishes at the vet. Take care.
