Signs to watch for

Burning and irritation of the mouth, tongue and lips
Heavy drooling
Vomiting
Trouble swallowing

Why it’s a problem

Toxic principle: Insoluble calcium oxalates.

Despite the name, the peace lily is not a true lily. The ASPCA notes its crystals aren’t absorbed into the body, so they don’t cause the kidney damage that true lilies cause in cats.
