Correction.
Bill Berloni's focus is on using rescue animals and he so whenever possible. On some occasion, he must source an animal from elsewhere - ie, the lambs for Gypsy, piglets for Alice in Wonderland. If at all possible, Bill Berloni will use a rescue animal, and he and his family take very, very good care of them, as do their trainers and handlers.
I highly recommend getting his book BROADWAY TAILS.
