We just recently bought 2 hamsters a couple weeks ago and were told they are brothers. they scoffle around all happy like until this morn... One attacked the other pretty badly, the victoms eye was nearly scratched out. Were taking him to the vet. i was wondering if a second cage should be bought or can they still be together? They both have alot of room to roam and alot of food so im not sure if it was a territorial or food issue..... but one was deffinatly acttacking and the other was just trying to get away... any suggestions?
