Size Matters?

So my male ball was born this past summer. I got him in late aug. On Sept 14 I finally got a scale and he weighed 150 grams. He is now as of today up to 217 grams. Does this seem too slow? I am feeding one adult mouse every 6 to 7 days. Is it time to jump to a small rat or rat fuzzy *and do any pet stores carry rat fuzzys? I really don't need 50 at a time....
Thanks everyone.
I really wish there was a guide for ball feeding like there is for corns. *hint hint people*

Well it really depends on you and how much and how fast you would like them to grow. There is nothing wrong with feeding once a week and alot of people only feed mice for the entire life of there snakes. Personally i feed what i would call small weaned rats, and i feed every 4-5 days for the babies and do one small rat once a week for yearlings.

Yeah i'd say so...wait till next year :)

BP all grow at a different rate, what matter is that your BP are healthy and have a good body weight

1 Adult mouse once a week is enough food for your BP.

I usually start offering a second mouse (for the mousers) at about 500 grams if that helps.

My new mojave was born Aug 4 and weighs 200 grams - I'm happy with his size. I'm feeding live rat pups (eyes and ears opened for a couple of days)
