Hi I’m new to this! I have 2 hamsters kept separately, 1 year old Gus and 3 month old(?) Minnie. Gus is a very relaxed friendly hamster but Minnie is the complete opposite... Minnie was very calm when we got her let you stroke her and was picked up a couple times she has done a complete 180 and is terrified of everything can’t even walk past the cage with out her jumping. Gus never did this and when I say jumping she is bolting around the cage and actually flipping over. I don’t know what to so because I feel it may be stressing Gus out and that’s the last thing I want. Feel like she’s gunna have heart failure or something. Need some advice on what to do.
