Some people get very emotionally attached to pets, others do not, This isn't an answer, just a bit of advice from someone who has had a lot of pets, and dealt with a lot of grief from others losing theirs. If your SO is an "attacher", a rodent is not a good pet. Having your heart ripped apart every two years or less can be devastating. Maybe the two of you could pick out another pet together after the grieving process has subsided, something with a longer life span. —
