That's great for you taking these unwanted hams I bet they are happy that you were "in the right place at the right time"

I have to ask - what type of hamsters are they?

If they are not dwarves (syrian, teddy bear, fancy etc) they then must live one per cage, and should be separated immediately. Syrian hamsters will eventually fight to the death if housed together.

If you are not sure what type they are take a look at the dwarf and syrian hamsters on www.petwebsite.com
