Let's clear the air quickly, once and for all: Poinsettias are NOT highly toxic. They will not kill your cat or dog. They may, however, cause mild indigestion or vomiting if a signficant amount of the plant is ingested... much like many other popular houseplants would. But don't take my word for it! The ASPCA has written extensively on this issue.
