If bunnies count as exotic, of course we had Miss Hoppy, bunny extraordinaire and my avatar here. She was a house bunny (litter box trained, and hopped around freely) and lived to be 11. Before her, for "exotic" pets, we had a Siberian Dwarf hamster, Vadim, adopted when his mom couldn't give him the attention he needed, a baby snapping turtle, Panzer, a Painted Turtle Rudi, many tropical fish, and most exotic, we "pet sat" for two chameleons for a couple weeks once!
