Ever noticed your cat dragging their bottom across the floor? Overgrooming their tail and back end? Your cat may be having problems with their anal glands.

Although scooting and anal (bottom) irritation are often attributed to worms, that’s not always the cause, especially for indoor cats.

Let’s take a closer look at the slightly awkward (but very important) topic of your cat’s bottom. Is it glamorous? ‘fraid not. Is it a common problem? Likely more than we realise. Can anything be done? Read on.

In this comprehensive guide, I'll explain the cause of anal gland issues, how to recognise them and when to seek veterinary help.

What are cats’ anal glands and why do they have them?

Cats have two small sacs just inside their bottom. If you think of the bottom as a clock(!), they’re located at roughly the 4 o’clock and 8 o’clock positions.

The anal glands produce a thick smelly liquid that’s released in tiny amounts when your cat passes a stool. Its likely roles include:

  • Scent marking their territory 

  • Individual communication and recognition - your cat’s social media profile

  • A smelly defence mechanism when your cat feels stressed or threatened, such as at the vets

Anal glands usually empty naturally when your cat passes a firm stool. When the system is working, nobody notices. When it isn’t, well, that’s when things get…‘noticeable’.

The root causes: 7 reasons your cat’s anal sacs get blocked

Anal glands start to cause trouble if they don’t empty properly. 

Possible reasons include:

  1. Passing soft stools or diarrhoea: Don’t squeeze the glands enough to empty them

  2. Eating a low-fibre or poor-quality diet: Leading to small or soft stools

  3. Passing infrequent bowel movements: Gland contents not expelled regularly

  4. Suffering from allergies (food or environmental): Causes inflammation and increased secretions

  5. Having skin disease or gut issues (IBD): Interferes with normal gland function

  6. Being overweight or obese: Reduces the strength and efficiency of muscles around the glands

  7. Getting into older age, being less active: Also impacts muscle strength

Over time, this progresses to:

  • Overly-full glands

  • Impaction: Anal glands become blocked with thick fluid and debris

  • Inflammation (anal sacculitis): irritated glands and discomfort

  • Infection: bacteria invade the glands

  • Anal gland abscess: A painful swelling close to the anus that may eventually burst

7 clues your cat might have anal gland problems

Cats are often more subtle about this than dogs, but there are still clear signs:

  1. Scooting or dragging their bottom

  2. Licking excessively or biting under and around their tail

  3. Losing hair around the tail base or the back of their back legs

  4. Chasing their tail, restlessness, agitation

  5. Straining or discomfort when passing stool in the litter tray

  6. Developing a sudden unpleasant fishy smell

  7. Swelling, redness or discharge next to the anus

The fishy smell explained

That distinctive smell isn’t your imagination and it’s too persistent and nasty to be flatulence (farting). Anal gland fluid is normally released in tiny amounts, so you don’t notice it. But when glands get full or infected and begin to leak, the smell becomes rather hard to ignore.

What happens if you ignore anal gland problems?

Anal gland problems in cats rarely get better on their own.

Left untreated, they can lead to:

  • Infection

  • Abscess formation

  • Severe pain

  • Rupture and chronic or recurring difficulties

A red, painful swelling under your cat’s tail suggests they may have an abscess. Sometimes anal gland abscesses will burst through the skin, creating an open wound leaking smelly pus and blood next to the anus. 

Seek help from a vet as soon as possible if your cat shows symptoms of an anal gland abscess.

5 ways vets treat anal gland problems in cats

1. Manually express the anal glands

  • A quick (if slightly undignified) procedure to empty them

  • Often provides immediate relief, but rarely appreciated by our feline friends

  • Symptoms will usually resolve within 24 hours

2. Flush the glands

  • Flushing the glands clears away trapped contents and blockages

  • For severe or recurrent problems. 

  • Your cat will be sedated for this procedure

3. Treat pain and infection

4. Investigate underlying causes

If problems keep coming back, your vet may check for

  • Allergies

  • Problems with their diet

  • Chronic gut/digestive diseases, especially IBD

Should you empty your cat’s glands at home?

Owners sometimes ask us this question, especially for dogs. It’s a controversial topic. But for cats, the answer is a clear No! Not without veterinary guidance.

Cats are much less likely to tolerate this procedure than dogs are. 

  • Poor or incorrect techniques can cause pain, burst glands, chronic inflammation or infection.

  • Also, routine emptying ‘just in case’ can cause irritation and isn’t recommended for most cats.

  • Healthy glands usually manage themselves.

Can you prevent anal gland problems in cats?

Sometimes - yes. Helpful measures include:

Feeding a healthy diet for healthy stools 

  • A complete, balanced diet, appropriate for your cat's age, breed and lifestyle.

  • Firm stools help to empty the glands naturally.

Supporting gut health

  • Fibre supplements can be beneficial: pumpkin or vet-recommended products.

  • Managing digestive issues: special diet, digestive supplements, prescription medication - as advised by your vet.

Managing weight and activity

  • Keep your cat slim and fit, with a healthy body condition.

  • Provide environmental enrichment for indoor cats: toys and interactive games to act out normal behaviours.

Managing allergies

  • Identify and control any food or environmental triggers.

  • Keep up-to-date with regular parasite preventive care.

  • Follow veterinary advice for prescription diets and supplements where needed.

Regular monitoring

  • Look out for early signs, such as licking or scooting.

  • Treat any issues as soon as they arise.

When to reach out to a vet

Seek urgent help (within 12 to 24 hours) if your cat is bleeding or in severe pain.

Contact a vet as soon as possible if your cat:

  • Is scooting or licking their bottom and tail repeatedly

  • Shows discomfort (agitation, vocalising) when passing stool

  • Develops a bad smell

  • Has swelling, redness or discharge near their anus

Treating anal glands early is relatively straightforward. Treating chronic or neglected problems is not.

Final thoughts

Anal gland problems in cats may not be the most pleasant topic. But your cat’s anal gland health is important. Most cases are quick and straightforward to treat and resolve completely if they’re caught early.

So if your cat starts paying a little too much attention to their back end, it’s not just odd behaviour. It’s communication. And it’s well worth listening to.
