Because of their low food and water intake, they produce little waste or urine. Life Span Hamsters rarely live longer than 18-24 months. If you need to move the hamster and it is not tame, then scooping it up into a small plastic container is okay, but generally just picking it up with both hands and supporting its hind end will allow the hamster to feel secure. The skin on the back of the neck is loose and may be used to aid handling. Do not use the tail.
Hamsters are very healthy animals.
They may hibernate for other reasons not understood.
