I adopted my last Russian dwarf from PAH for a £5 donation. He was returned to the store by the person who bought two together and he was the bully apparently!
That`s him in my avatar image (RIP) wee man. He was a cheeky wee soul who wasn`t really into handling, but as he grew older, he was much more settled. Rescue/rehomed hamsters in my opinion are the way to go.
