as for weights.....they are as big as a big gerbil......I would think they weighed in at around 250 grams 200??......
I have weighed mice and found they run alot of variables even if they look the same.....alot of my big mice weighed around 85 grams........I have had one go 111 grams fat and gravid......I weighed another pregnant one at around 95.......small mice run 35 grams even.........
......adult balls can eat any sized african rat.......and I plan on feeding one at a time usually.......maybe 2 on the fat girls.....they weigh at least 3500 to 4000 grams I think....
.......the plan would be to use them IF necessary only.......and once you start the ball may never switch back to anything else......
I have used chinese and russian hamsters and white footed mice(Peromyscus) and have had the balls never eat mice again except for maybe one goof feeding month a year........
I use what they want.......I breed everything.......too many species of mammals.........and feed them all.....
gerbils,chinese,russian,mice,rat,africans now...I have used spiny mice and syrian hamsters alot too......
......IF AT ALL POSSIBLE FEED MICE OR RATS AND NEVER SHOW THE OTHER STUFF TO ANY SNAKE........THEY WAY THEY WON'T EVER GET HOOKED........
I know guys that get rid of any snake that won't accept rats.......
