I am a new member, I found this site while looking for answers to the question of keeping a chinny alone/introducing a new chinny. This morning I found that my 12 year old Jersey woollie bunny male had passed away , he had lived for years with my Male chinchilla. A definite Odd couple, but they enjoyed each other and got along just fine. I worry about the lone survivor and wonder if I should consider getting him a playmate.
