hmm. . .i might pass this question on to my vet,she could then ask the rabbit experts at MSU what they think. i amdigging deep into this as now i am super curious. . .
i know that yucca extract is used in feeds, and that there are 2 otherforms of it- the plant and flower, and theroot. what i havefound is the root. . .
in further digging, i have learned (ifi read the factsright,and if there is any truth to the websites i lookedat)that the yucca plant is a member of the agave family,according to the san diego chapter of HRS, the only part of the agavethat is toxic is the leaves.
in google i typed in simply "toxic rabbit yucca plant" and came up withlots of finds. . .one is from i-eat-plants lab. which is part of theoklahoma state university vet studies. it is very interesting, but ican find no information about what the study is for (dogs, cats,rabbits, ect) i think i am going to e-mail them for futher informationon the site, because if it was for rabbits or such, it could be a greattool to use(as it is all about common house plants). here is the url:

here is what it had to say about the yucca plant:
Common Name: Spineless Yucca, Soapweed, Spanish Bayonet
Scientific Name: Yucca sp.
Family Name: Agavaceae
Toxic Principle: Spines, Furostanols, Leaves, Saponins [steroidal], Spirostanols sarsasapogenin
Clinical Signs: Vomiting, Bloat, Diarrhea, Nausea, Mechanical damage
but once again, i find no information about the root (unless saponinsor spirostanols-sarsasapogenin are scientific terms for root). also,this is for SPINELESS yucca, there are many different kinds of yuccaplant and from what i have gained some are toxic to humans, whileothers aren't (i have no idea if they is relevent to the rabbit world)
some questions that i am yet to find the answer to isweredoes the yucca extract come from? (the plant, or the root) and how muchin rabbit food is safe? (obviously i want to know this to start lookingat feeds. . .)
part of the problem i am having is that without the knowledge of somebasic vet terminology (orbiology terminology) some ofthisstuff i am ready simply doesn't make sense. i am going tocall my vet tomorrow, as her if she has anything in her knowledge, orbooks, that will lead me to the correct answers, and if shedoesn't,see if she knows of anyone that does. . .
i am going to keep looking around. . . it makes sense that it is toxic,as it is also a member of the lily family and (correct me if i amwrong) but lilies are toxic to rabbits. . .
hopefully i will find the truth to this one. . .
