Remember a dwarf retic still can easily hit 14'. Dwarf isn't that much smaller than mainlands. If you want something under 10', then you are going to want a super dwarf. Caesar is 37.5 SD, 31.5 dwarf and 31% mainland from Vital and he is a little over 4' now at 8 months old. Might be bigger as he is in shed and being antisocial in his hide. And that is feeding him every 4-7 days. The best thing is find out how big the parents were. That is why I say go through a reputable breeder. Sure you might spend a little more but you will be getting exactly what you want.
