Is lemon thyme safe for cats and dogs?
Yes — ASPCA non-toxic to both cats and dogs. Lemon Thyme is a sensible choice for a pet household; a curious nibble will not poison anyone. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. ASPCA-listed as non-toxic to cats, dogs and horses (Thyme, Thymus vulgaris, family Lamiaceae). The whole garden plant is safe to grow around pets; note that concentrated thyme essential oil is far stronger and should not be applied to animals.

What happens if a pet eats lemon thyme?
Because lemon thyme is non-toxic, a curious nibble will not poison a cat or dog. That said, no plant is meant to be eaten: a large quantity of any foliage can still cause mild, short-lived stomach upset or vomiting simply through fibre and volume. Persistent vomiting, diarrhoea, or lethargy after eating any plant is always worth a call to your vet, because the reaction may be to soil, fertiliser, or a pesticide rather than the plant itself.
What to do if your pet ate lemon thyme
- Remove any plant material from your pet's mouth and move lemon thyme out of reach.
- Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
- Do not induce vomiting unless a vet or poison-control specialist instructs you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
- Bring a leaf or photo of lemon thyme to the appointment so it can be treated correctly.
