Oh my, precious little Evelyn. We are so sorry to hear the sad news. And you really don't know that either of the dogs did anything wrong. The cage could have been accidently knocked over and Evelyn was hurt in the accident. Lilly, trying to rescue her, picked up the dead hamster body and was trying to get it some help by bringing it to the pet sitter. "Here, please help, Evelyn!" I think that this scenerio makes more sense. I know whatever the cause, you all will miss the little Evelyn.
