I'm a bit curious if any ever observed this before with their garter snakes. I just fed three of my adult male garters in their terrarium a helping of small fish as a snack. Once they were full, or rather, refused to take any more, each one at a time went inside the watering bowl and proceeded to swim around in circles, as if trying to clean themselves. Some took a second dipping and rubbed their faces alongside the bowl as if trying to get something off their face.

Were they aware of their new fishy smell and was simply trying to clean themselves? I'm curious, never seen them bathe themselves after eating pinkies/fuzzies before.
