General guidance — not a diagnosis. When in doubt, call your vet.
What red tissue protruding from the anus can mean
Red or pink tissue coming through your cat's anus may be a rectal prolapse and needs prompt veterinary assessment. Contact a clinic now, describe what you see, and do not push, pull, squeeze, or medicate it. This guide explains observations to report; it cannot diagnose your cat.
Rectal prolapse is protruding rectal tissue, which can become damaged or necrotic.[1] Do not wait for it to become larger.
Describe the finding as “tissue protruding from the anus,” rather than deciding it is a hemorrhoid. If you are unsure where the material originates, say so. Uncertainty is a reason to have the area examined, not to handle it more closely.
Protruding tissue versus a swelling beside the anus
Location is useful information, but it is not a home diagnostic test. Without touching the area, note whether you see a central ring or tube coming through the opening, a lump beside it, an open wound, or material caught in the fur.
Anal sac disease can produce discomfort, scooting, licking, painful defecation, discoloration, and draining tracts; examination may be needed to distinguish inflammation from other lesions.[2] The cat scooting guide explains that separate pattern. Do not assume that every change under the tail needs gland expression.
Blood on stool is also different from a visible tissue protrusion. If both occur, report both. The blood-in-stool guide can help you describe the stool, but a stool-color description does not explain what is protruding.
What to record without delaying the visit
Call first, then gather details while arranging transport. A short description is enough to begin: “My cat has tissue sticking out of the anus; it appeared after using the litter box.” Tell the receptionist if your cat is crying, repeatedly straining, vomiting, or becoming weak.
Useful observations include:
- When you first noticed it and whether it stays visible or appears during defecation.
- Whether your cat has passed stool, urine, both, or neither.
- Recent diarrhea, hard stool, repeated litter-box trips, or a previous similar episode.
- Any licking, dragging, visible wound, discharge, or change in appetite.
Persistent straining from intestinal, anorectal, or urinary disease can accompany rectal prolapse.[3] Do not label every unsuccessful litter-box trip constipation; report actual output. The urinary blockage guide covers the urinary emergency that can otherwise be mistaken for a stool problem.
Take a photo only if it is easy and safe. Do not repeatedly lift the tail, restrain a distressed cat for a better picture, or try to measure the tissue. Keep the original photo available for the clinic; note the time it was taken.
What not to attempt and what to ask the clinic
Do not pull on anything attached to the anus, insert an object, express the glands, or use a human hemorrhoid product. Avoid home enemas, leftover medicines, and internet instructions for reducing swelling or replacing tissue. Ask the clinic for specific transport instructions, including whether anything should be applied or whether food should be withheld.
Veterinary management addresses the prolapse and its cause. Feline reports describe recurrence associated with anal abnormalities, showing why treating the visible protrusion alone may not resolve every case.[3] Ask what follow-up will check, what stool and urine observations matter, and whom to call if tissue reappears.
When to See a Vet
- Tissue is protruding from the anus, even if your cat is otherwise alert: contact a clinic immediately for prompt assessment.[1]
- The exposed tissue is becoming dark, swollen, ulcerated, or visibly bleeding: seek urgent veterinary care.[1]
- Your cat repeatedly strains and you cannot confirm urine output: tell an emergency clinic immediately.
- Your cat collapses, cannot stand, or has severe distress while tissue is protruding: go to an emergency clinic.
For cat owners
An article can't ask about your cat.
Describe what you're seeing. You'll get a few follow-up questions about your cat, then where it lands — vet today, watch closely, or no visit needed — and what to do at home meanwhile.
Frequently Asked Questions
Is red tissue sticking out of my cat's anus an emergency?
Contact a veterinarian immediately for directions and prompt assessment. Do not wait for the tissue to turn dark: exposed rectal tissue can become damaged.[1] Tell the clinic whether your cat is still passing urine and stool.
Could it be an anal gland problem instead of a prolapse?
Anal sac disease can cause pain, swelling, discharge, and licking around the anus.[2] A photo may help the clinic understand what you mean, but it cannot replace an examination. Describe whether the change is beside the opening or appears to come through it.
Can I push a cat's prolapse back in at home?
No. Do not insert a finger, swab, or other object, and do not attempt a reduction. Ask the clinic how to transport your cat; do not turn instructions intended for veterinary professionals into a home procedure.
Why does the tissue come out only when my cat poops?
Intermittent protrusion still needs assessment. A published feline case report described rectal mucosa protruding during defecation in cats with anal abnormalities.[3] Record the pattern rather than assuming that disappearance means the problem is solved.
Can rectal prolapse return after veterinary treatment?
Yes; recurrent prolapse has been reported in cats, including cats with anal sphincter abnormalities.[3] Ask for a written follow-up plan addressing the underlying problem as well as the repaired tissue. Contact the treating clinic if you see another protrusion.
What should I bring to the appointment?
Bring available photos, the time the change first appeared, a list of medicines and parasite products, and details of stool and urine output. Include previous prolapse or pelvic-injury records if available. Ask the clinic whether it wants a stool sample and whether your cat should eat before arrival.
