Hello Katelyn. I am sorry about Molly, but really glad you now have Sunny. Yes, it is perfectly normal for a hammy to sleep outside a cage. My Nutmeg does it all the time. Not to worry
. You were right to only have the one hammy in the cage. They don't get lonely. She will get used to her home soon enough. As for when you can start handling her, wait a couple of days and then you can start getting her used to you. I think as long as you are slow and gentle, Sunny shouldn't bite. Most hammies bite because they are frightened. If you have any other questions don''t hesitate to ask. Someone will be sure to have the answer.
