Any other hoggie do this?

I have no idea if this has been studied, but I'd hypothesize that colubrids use barometric pressure as a signal for brumation. I bet that you could get a high percentage of breeding age colubrids to go off feed in the middle of summer solely by changing the barometric pressure in the room they are kept (ie raise pressure to winter levels). Of course, it'd take a bio lab with specialized equipment to pull it off...

There's nothing wrong with double checking husbandry at least seasonally or especially if a behavioural shift is observed. I just don't worry much about it around this time of year.
