Why does my cat's rear smell foul and leak clear, awful liquid?

Updated on September 23rd, 2025

My 10 month old cat has this foul smell coming from his rear. He doesn’t have poop or any stains on his butt. His stool is also very normal, he eats well and he’s very active. His fur is short and he’s 10lbs. Very healthy looking cat. But there’s this clear liquid that comes from his butt that smells extremely horrid. it got on my arm once from holding him and it’s all over a blanket he sleeps on. I’d attach photos but it’s clear.

It sounds like it may be fluid from the anal glands. Most cats do not have anal gland issues but some do. I recommend to have the anal glands expressed by his veterinarian. He may need this done periodically.
There is also a supplement called Glandex that will help his body to naturally express the glands during a bowel movement. You will feed this to him every day.
I hope this is helpful and please feel free to post any additional questions.
