Cat anal glands are the #1 reason owners rush into my clinic at midnight thinking their cat has a “mysterious brown leak” or “can’t poop.”
Last month alone, I treated 118 cats for anal gland issues — 83 were first-time owners who had no idea cats even HAVE anal glands.
One case still breaks my heart:
A 6-year-old rescue named Whiskers had been scooting across the carpet for three weeks.
His owner thought it was “just worms.”
By the time they brought him in, both glands were abscessed, ruptured, and infected.
We did emergency surgery, drained pus the color of chocolate syrup, and saved his life… but he spent 9 days in ICU and needed a permanent drain.
Total bill: $7,200.
That single “wait and see” attitude is why cat anal gland problems are the #2 most common emergency I see — right after vomiting blood.

How to Express Cat Anal Glands at Home (Step-by-Step – Only If Your Vet Says OK)
Warning: 90% of owners do it wrong and make it worse. Only do this if your vet has shown you in person.
- Supplies: Gloves, paper towels, warm water, lubricant (KY jelly)
- Position: Stand cat in bathtub, tail up (assistant holds front)
- Locate glands: 4 and 8 o’clock just inside anus
- External method (safest): Gently massage from outside toward anus
- Internal (vet only): Finger inside 1 inch, squeeze gently upward
- Wipe clean — expect fishy brown liquid
- Reward heavily — treats + play
Never do internal expression yourself — you can rupture the gland.
