BRIEF: Is mother-in-law tongue poisonous to cats?
Is the plant commonly called mother-in-law tongue (long, skinny, thick leaves - green with some white marbling) harmful to cats??
Yes, it can give any mammal that munches on it a very bad afternoon. The oxylate crystals cause intense pain to the mouth and a protease enzyme adds to the damage. I don't think this plant is fatal, but it is not something an animal or a child would try to chew on twice!!!!
