The Butler’s garter I referred to in previous entries (here and here) has now died. She had refused to eat earthworms over the weekend, which just does not happen with this species, so we knew her time had run out.
We’ll do a necroscopy this evening and find out what killed her.
Overall, though, I’m neither disappointed nor embarrassed (unless the necroscopy shows that we fucked up somehow). Six years is an extremely good run for this species, three times as long as the record. And the remaining Butler’s garter is still going very strong — she’s the big, hungry one who likes to bite.
At some point I should write an article on the long-term care of this species.
