Are Valerian root toxic to cats?
Yes. Valerian root (<em>Valeriana officinalis</em>) affects cats similarly to catnip — many get euphoric and playful. It's non-toxic in the amounts cats usually ingest and is a common catnip alternative in UK pet toys.
What's the full picture?
Valerian root contains actinidine, a compound that triggers a catnip-like response in most cats. Unlike catnip, valerian tends to energise rather than relax — useful for under-stimulated indoor cats.
Valerian root for humans (as a sleep supplement) is compressed tablets with added ingredients; cats should only have plain dried root or pet-specific valerian toys. Human supplements may contain melatonin or other additives not safe for cats.
A freshly cut valerian plant has a strong distinctive smell that has been described as 'dirty socks' — cats love it.

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.
Entries are reviewed and updated as new research emerges. Spotted an error? Let us know — corrections are investigated and applied within 24 hours. For more context on how we work, see about and our full disclaimer.
