I cannot get Jerry neutered due to his health and age, or a female spayed due to the very high cost, but my vet has mentioned a few times, it's too bad Jerry can't have a companion. She suggested moving his cage close to a hamster. He was near my Chinese hamster but Beanie is not very active, so I put him by my Syrian. The hamsters are nocturnal and he is not. I do realize this is not for the hamster's benefit. lol So, I was wondering if Jerry would enjoy having girl mice next to him in another cage, or would that be torture or pointless since he couldn't cuddle with them or groom together? He's depressed with the collar on his neck. I know that's just temporary but adds to his stressed-induced scratching. Thanks in advance for your input!
