what size should I feed??

my BP is about 18 inches right now i'd say, give or take an inch or so. Anyway, when I bought him they were feeding him mouse pinkies, I knew that was too small. Knowing the pinkies were too small, I bought mouse fuzzies. I didn't like that either, fed him twice on them but again knew they were too small. Just this past thursday I fed him a hopper, and I am satisfied with that, but is that the right size or maybe should I go to a small mouse rather than the hopper? Any advice?

Typically it is the size of the snakes "girth" or widest point. Same width as the mouse/rat.

If you have a scale to weigh your snake then take 10~15% of the weight of the snake and go to www.rodentpro.com select the kind of rodent and use the weight from before and use that as what size prey you get.

My snakes are probably the same size as yours, maybe a tad bigger, and I feed them rat pups.
