Confronting mortality

Alas the colony of ageing hamsters at home...actually only two survivors now :( We brought Friendly to the vet for a closed eye, which is probably the result of her being a dirty girl. To our horror, the vet discovered a mass in her stomach, and suggested an x ray. Our dilemma is, the mass requires surgery and she is already so old. The vet warned that she might have to be put down *sob* during the surgery, depending on the nature of the mass *sob* But not operating is essentially letting her go gently into the night... I really don't know. I feel...so...very tired.
