I do no think they need vet visit as a condition of release. I have picked up 4 from this shelter. These buns are young, and I believe all female, but if there is a male among them, they are at breeding age. You would have to keep them apart, or take my offer of spay/neuter or be rapidly overrun. I think the rex was adopted, and the two left are the Angora/Woolie/Lionheads? . I am hoping for a rescue or forever home ideally. Easter is early, and if you can only hold them for a month or so, it puts them in the rush of Easter mistakes. Of course, they wil live! So ideal may be far from reality at this point! They are easy going about bun adoptions as far as timing. Better to adjust a time frame,than lose an animal. As I said, they are great at this shelter.
