Common questions

Is alyssum related to the toxic plants called alyssum?

The name gets shared around — hoary alyssum (Berteroa) is a different plant that affects horses. Sweet alyssum (Lobularia) itself is safe for cats and dogs.

Does the fragrance bother cats?

No — the honey scent is harmless to pets and actually attracts pollinators, which can be its own entertainment for a window-watching cat.
