Common questions

Can a cat chew lilac flowers safely?

Yes. The blooms are non-toxic and many cats only sniff them. A heavy snack of flowers might cause mild vomiting from sheer volume.

Why do some sources say lilac is toxic?

Confusion with chinaberry, also called Persian lilac, is the usual cause. True Syringa lilac is safe; Melia azedarach is deadly.
