Chinchilla
Chinchillas can be extremely difficult to handle and display a variety of behaviors when it comes to telling you to back off. Normally a very quiet animal, barking and high-pitched squeaking signal annoyance and disapproval. “Fur slipping” is the act where a chinchilla will lose the fur in the area where it was improperly touched or handled. They will also engage in urine spraying to deter potential predators from getting too close.
