Is Cannabis / CBD / edibles dangerous for cats?
No. Cats exposed to cannabis — smoke, edibles, or CBD products — can develop significant toxicity. THC causes disorientation, tremors, low temperature, and in larger doses, seizures. Cannabis-infused edibles often combine THC with chocolate or xylitol.

What's the full picture?
Cats are very sensitive to THC. Even passive smoke exposure in a small room can cause signs; ingestion of edibles is a medical emergency because of combined risks (THC + chocolate + often xylitol).
CBD products for pets are increasingly sold in the UK. Legitimate products have negligible THC and are used under veterinary supervision, but human CBD oil, gummies, or tinctures may contain significant THC.
Cats typically develop low body temperature (not high, unlike caffeine), slow heart rate, and profound disorientation. A stumbling, 'drunk' cat with dilated pupils and dribbling is a classic presentation.

Questions owners ask
How much cannabis exposure is dangerous to a cat?
Cats are considerably more sensitive to THC than dogs or humans, so even passive smoke exposure in a small room can cause noticeable signs, and a genuine edible ingestion is treated as a medical emergency regardless of the amount, partly because edibles so often combine THC with chocolate or xylitol as well.
How would I tell cannabis toxicity apart from other kinds of poisoning in my cat?
The distinctive pattern is a combination of low body temperature and a slow heart rate alongside profound disorientation and dribbling urine — this is notably different from stimulant toxicities (caffeine, pseudoephedrine, chocolate) which typically cause a fast heart rate and high temperature instead. A wobbly, 'drunk'-looking cat with dilated pupils and dribbling is the classic presentation, and it's worth telling your vet directly if you suspect cannabis exposure rather than assuming it's a different poisoning, since the supportive treatment differs.
Are legitimate pet CBD products actually safe, unlike human cannabis products?
Products specifically formulated and marketed for pets, with verified low or negligible THC content, are generally used safely under veterinary guidance for conditions like anxiety or chronic pain. The risk described in this entry relates to human-intended products — THC-containing edibles, tinctures, or smoke exposure — not properly formulated pet CBD, so always check a product is genuinely pet-specific and vet-approved before using it, rather than assuming any CBD product is equivalent.

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.
