Hey Ethan,
I have to agree with Kara, one of the biggest mistakes made by some, albeit, keepers, is to feed over sized prey or food items to their animals. In this case bloods and short-tails. I only feed jumbo rats to my adults and they are all thriving and putting on weight, and shedding regularly which is a good indication that they are growing. Most get fed every 14-20 days. Jumbo rats, and if you wish "super jumbos, are large enough for any 20 -35 Lb. blood/short-tail, anything larger than that to me is over kill.
