So my Herp vet informed me that I should be feeding small adult mice versus rat pups to my 230 gram male since adult feeders are more nutritious than young feeders due to what they eat. Basically there is more calcium in adults because they are eating and not just taking in milk. Anyone familiar with this? I hate to get him on mice and then later have to feed more if he refuses adult rats later.... I am feeding 2 f/t rat pups every 7 days and he is eating great. Still have a lot left in that size since I went to the Sac reptile show and purchased them there.
