My 3-week-old kitten's anus is red, protruding, and bleeding.

Updated On September 23rd, 2025

Pet's info: Cat | American Bobtail | Female | unspayed | 1 month and 2 days old | 1lb

New kitten 3-4 weeks old. Owner said , kitten was wormed and had eaten soft food. Been feeding 1-1 1/2 tsp of soft pate cat/kitten food. She doesn’t want to drink much water. Have given her whole milk twice. I noticed blood droplets on her bed. Anus appears to protrude a little and very red.Dont know if shes too young for food and milk or dehydrated. Her poop seems ok and haven’t noticed any blood in it or the litter tray. She is highly active. Not lethargic. I’m just worried about her rectum

She is still very young to be away from her mummy so if you are having trouble getting fluids into her You may need to go to the vet or pet shop and buy kitten formula milk for her. Ensure that you are feeding a high quality wet kitten food also. Under no circumstances should you ever feed a cat cow's milk, unfortunately this I a very common error. Cats cannot process lactose properly and it can really upset their tummies. As for the anus, it is hard to make out from photos but it certainly looks very inflamed and sore. This could be due to swelling from straining to defecate due to worms or diet intolerance such as the milk. This could lead to more serious issues such as infection or prolapse. The best thing would be to take this little one to the vet asap for a thorough check over. The vet can decide what treatment is needed for the anus. They can also worm the kitten to be safe, advise on appropriate diet and make sure it is generally a healthy kitten. Best of luck with her.
