Many years ago I volunteered time at the local offices of the American Cancer Society. One of the other people there was a woman who participated in a unique adoption opportunity. In conjunction with one of the local zoos, she took physical custody of two large animals pronounced something like “bentarons”. They were large (about 7’ long) creatures that walked on all fours and were furry, shaped a bit like an aligator or crocodile with what looked to be a powerful tail. IIRC, they were from Southeast Asia and were tree dwellers (which kinda surprised me as they looked to be about 150lbs.)
