FAQ
Is thyme safe for dogs as well as cats?
Yes. The ASPCA lists Thymus vulgaris as non-toxic to cats, dogs, and horses, with "non-toxic" in the toxic-principle field itself, so thyme is S0 Safe on both our cat and dog pages. The entry's alternative names — common thyme, garden thyme, German thyme — are all the same species and all covered. It is one of five herbs on our index graded S0 for cats, alongside basil, rosemary, sage, and cilantro, which together make a kitchen windowsill a mixed household can plant without a plan. A dog that eats a mouthful of thyme has eaten a mouthful of thyme, nothing more.
