Here is what I use BP above 500 grams and up to 900/1000 grams I use large for BP 1000 up to 1500/1600 I use X-Large for BP over 1600 grams I use Small kitty litter pans from Walmart.

thanks a lot

p.s. im was never big on milk snakes (or any colubrids)
but after seeing your Albino Honduran I am looking into them :) I hope to pick one up after I get myself a carpet python in January.
