It can handle the weight of any snakes that I can fit in a bowl on top of it easy peasy.
It's sensitive enough that I weigh my crested geckos with it.
I just wish I could find a way to weigh 4 foot long carpet pythons that are too noodle-y for a typical scale, but not heavy enough to use the "weigh-yourself-on-the-bathroom-scale-while-holding-snake-" trick.
Could you put them in a pillow case? ( Put the pillow case on the scale tare it) Then put the snake in pillow case?
