Is Glue / adhesives dangerous for cats?
No — particularly polyurethane wood glue (Gorilla Glue and similar). PU glues expand dramatically on contact with stomach moisture, creating a large solid mass that requires surgery. Other glues cause GI upset.

Key facts
- Verdict: No — dangerous to cats. Glue / adhesives should never be given deliberately.
- Category: Chemical
- Onset: Signs can start hours (pu glue) — see the full timeline below.
- If it's already happened: Call your vet now, or the Animal PoisonLine on 01202 509000 (24/7, charges apply) — see the emergency steps below.
If your cat has just eaten glue / adhesives
- Don't try to induce vomiting — PU glue expansion is worse coming back up.
- Identify the product (brand and type) and take packaging to the vet.
- Go to your vet immediately for any PU/polyurethane glue ingestion.
- Call the Animal PoisonLine on 01202 509000.
What's the full picture?
Polyurethane wood glues (Gorilla Glue, No Nonsense, Everbuild PU) are the specific emergency. They react with moisture to expand 3–4x in volume — turning a small swallowed amount into a stomach-filling solid ball that surgically must be removed.
Superglue (cyanoacrylate) causes mouth burns and bonds to tongue/skin on contact. Rarely a serious ingestion risk because cats drop it fast.
Standard PVA craft glue (Pritt, Copydex) is low-toxicity but causes GI upset. Epoxy and other industrial adhesives are a mix of concerns — always call your vet.

Questions owners ask
How much glue is actually dangerous to a cat?
It depends entirely on the type. A small amount of standard PVA craft glue is low-toxicity and mainly causes mild GI upset. Polyurethane wood glues (Gorilla Glue and similar) are dangerous in even small amounts because they expand 3–4 times in volume once they contact stomach moisture, turning a modest swallowed amount into a large, solid, surgically-removable mass.
My cat's mouth is stuck together after contact with superglue — what should I do?
Don't try to force the mouth open or pull tissue apart, since this can cause tearing. Bring your cat to the vet, who can safely use appropriate solvents or careful manipulation to release bonded tissue. Superglue itself rarely causes serious internal poisoning since so little is typically swallowed before it bonds, but the physical bonding to skin, fur, or the mouth needs professional handling rather than a DIY attempt at home.
Are there safer adhesive options to use in a cat household?
Standard PVA craft glue is meaningfully lower-risk than polyurethane wood glues like Gorilla Glue, so for household repairs or crafts, choosing PVA where the job allows reduces the risk if your cat investigates a drying glue container. Whatever adhesive you use, cap it immediately after use and store it out of reach rather than leaving it open on a work surface.
A bitter deterrent spray makes cables, bin lids, and cupboard edges taste unpleasant without harming your cat.

About this guidance
Every entry on this site is compiled from published UK veterinary toxicology sources — International Cat Care, Veterinary Poisons Information Service (VPIS) references, RCVS-registered practice materials, and peer-reviewed feline medicine literature. Where the evidence is mixed, we err on the cautious side because cats are unusually sensitive to many common substances that are harmless to humans and even to dogs.
This is general information written for UK cat owners. It is not personalised veterinary advice for your specific cat, their age, weight, medical history, or the exact exposure you're dealing with. If your cat has eaten something or is unwell, call your vet first. The Animal PoisonLine on 01202 509000 is available 24/7 for a small fee and can tell you whether an emergency visit is needed.
