How Big do Female Red Tails Usually Get?

[Bellabob]

Anytime, and when feeding multiple smaller prey items (i.e. when I'm finishing off a bag of f/t feeders before moving up a size or something) then I tend to go for the 10% - 15% of the snake's weight. So pick two (or however many) rats whose weights add up to about 10 or 15% of the snake's body weight and it should be fine and give them maybe every 10 or so days (but you could wait longer if you fed a little bit over the 10-15% in that feeding)

So I should weigh the snake, and feed her the right sized and right amount of prey items based on her weight? Sounds easy enough.
