Garter snakes are wonderful creatures, and very affectionate too.
I had a couple when I was a kid, but unfortunately, they're also incredible escape artists, and they both eventually escaped from my vivarium.
One I never saw again, and the second unfortunately made its way through the walls to the neighbour's house.
The father of the house, not knowing the snake was completely harmless, battered it to death.
I was very upset, although it was tempered with understanding, and a malevolent glee that this tiny creature had made this jerk scream like a school-girl.
