Is Yucca Plants Poisonous?
I have pet rats and one loves playing with the fallen leaf from Yucca plant, but are they poisonous?
"Typically, when dogs and cats ingest yucca, it results in mild vomiting and diarrhea.", from another article.
I would suggest you ask your vet just to be certain. Some sources say yucca is not harmful to dogs and cats, other sources say it is to some degree. I was told once that the difference between a dog/cat and a mouse/rat eating mouse/rat poison was that dog/cat could vomit it up and the rodent could not.
