They said by how high the kidney levels were it almost sounds like a toxic poisoning. I have no idea what she could get into...we don't keep plants indoors because I don't know what is toxic and what isn't so I don't really bother. We haven't had any chemicals or anything laying around. Nothing new...any none of my other pets are sick. They have a pen outside they can sit in but there aren't really any plants near by. I know lilies can cause kidney problems but there aren't any in her pen. There is a little bush near by but I duno what kind of plant it is...and it's been there for years (that's shes been going out there)
