Last week my last grandma and Cornelia's hamster died. Both were fairly old, grandma at 90+, and the hamster was an Elder Hamster, too.
Grandma surely didn't mind finally dying; the last few years she didn't really enjoy herself very much anymore - eyesight pretty much gone, too frail to do anything, breaking bones every couple of months and so on - but she still was lucid and happy about my (infrequent) postcards and even more infrequent calls.
The hamster never received any phonecalls from me, but I'm sure it had a good life in Cornelia's care nevertheless.
I wish both of them a happy next life, or happy sansara or whatever they may feel appropriate.
