got bit

ok so i fed my ball python a small mouse, i think it was to small, well later that night i was fixing the thermomter like always and he bit me, do you think shes still hungry

Yeah, he was probably still hungry. :)

should i be feeding him bigger mice?

You should feed between 10-15% of th snakes body weight.

how do i tell the weight?, is there a way with out a scale

There's no accurate way to tell a BP's weight without a scale. It'll be smart to invest in a cheap gram scale found in Walmart for like $20-$30. Or if you have a normal scale you can always find out the weight in grams by multiplying the weight by 454. Since there is roughly 454 grams in a pound, it's pretty simple to figure out. So if your BP weighs .73 of a pound, he would be 331 grams. Hope this helps.

Or you could just get a $15 food scale that measures up to 3,000 grams and has a tare button.

^ That is what I meant by a gram scale at Walmart. :) Either way it is very cheap/easy and will help you and your snake a lot.
