What happens if a pet eats madame lemoine lilac?
Because madame lemoine lilac 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.
