Just checked this aspca-website and found something about a "Japanese Show Lily" . Maybe this is the plant you're looking for? I hope not, because this one is even more dangerous:

Common Name: Japanese Show Lily
Scientific Name: Lilium sp.
Family: Liliaceae
Toxic Principle: unknown
Clinical signs: vomiting, inappetence, lethargy, kidney failure, and death is possible. Cats are only species known to be affected.
