The toxicity issue is from the live plant.   Before I started selling the Yucca “wheelies”, which are yucca chews, I did a research, discussed this thoroughly with the supplier, with my vet and a botonist.  I can’t speak for all yucca chews because I don’t sell other’s products, but in general, the dried yucca is safe. 

Check out another thread that had similar concerns – you’ll see my answer at the very bottom explaining in more detail about toxicity etc.

What you will find is the toxic scare of Yucca usually comes from one main source and that is the main list of toxic plants from the APSCA, and they don’t differentiate what part of plant it is, whether it’s been dried, and that really makes a difference.  That’s like saying apple trees are toxic, which you do have to be careful with the leaves and sticks should cut from the tree and dried out, but that doesn’t mean that the sticks from trees then are toxic.   Hope that makes sense.

So yucca is like a food? hmmm…interesting. We need to get more toys for Boston, she is getting bored and *destructive*….

Well yucca chews are chew toys usually. Though dried powdered yucca has been used in treatments and food, what we’re talking about are the toys that are used mostly for birds and small animals. Sort of a roundish soft wood (a bit softer than pine).  

No worries. it really is something that needs to be clarified more on the toxicity lists.

I had gotten 2 yucca chews from bb site and mine loved it.    As for eating it I have never been able to cook it right.  So I have not messed with it since then.
