Questions about Lemon Balm
Is lemon balm toxic to cats?
Lemon balm (Melissa officinalis) is non-toxic to cats. It is classified as generally safe, meaning exposure is not expected to cause poisoning or serious harm.
What happens if my cat eats lemon balm?
Most cats will have no reaction at all. If your cat eats a large amount of the fibrous leaves, mild vomiting or diarrhea is possible due to the bulk of plant material, not any toxic compound.
How much lemon balm is too much for a cat?
There is no established toxic dose because lemon balm is non-toxic. That said, non-toxic does not mean unlimited — large quantities of any fibrous herb can irritate a cat's digestive tract and cause temporary GI upset.
Should I call my vet if my cat ate lemon balm?
A small nibble requires no action. If your cat ate a large amount and shows persistent vomiting, diarrhea, or signs of distress, contact your veterinarian, as prolonged GI upset from any cause warrants a check-in.
