What this means for your cat
Cats are in the clear with Sawbrier — the NC State Extension Plant Toolbox lists Smilax glauca as non-toxic to cats. A nibble isn't a poisoning event; only large amounts of the fibrous, thorny stems would be likely to cause brief, self-limiting GI upset.

Questions about Sawbrier
Is sawbrier toxic to cats?
Sawbrier (Smilax glauca) is non-toxic to cats. It is classified as generally safe, meaning it does not contain compounds known to cause poisoning in cats.
What happens if my cat eats sawbrier?
No toxic symptoms are expected. If your cat eats a large amount of the fibrous plant material, it may experience mild vomiting or gastrointestinal upset due to the roughage, not any toxic principle.
Should I call the vet if my cat chewed on a sawbrier vine?
A small nibble is unlikely to require veterinary attention since the plant is non-toxic. If your cat ate a significant amount and is showing signs of distress such as repeated vomiting or lethargy, contact your veterinarian for guidance.
Can large amounts of sawbrier still cause problems for cats even though it's non-toxic?
Yes — non-toxic does not mean harmless in any quantity. The fibrous, woody stems of sawbrier can irritate a cat's digestive tract in large amounts, potentially causing mild vomiting or GI upset. Keep access limited even though there is no risk of poisoning.
