That's so sad, was he ... was he not loved enough? He seems a bit like this hamster I had to put in a separate tank once. He was mean and feisty and kept biting people, so they'd take him back.
It was horrible, he didn't want anyone to love him anymore :(
But I guess he found a home with this nice blonde lady. I hope that he doesn't bite her anymore.
I was so angry at the people, but... I guess everyone just really needs to be shown some kindness. This man certainly sounds like he needs some, to me!
