Thank you so much for all that info! I have to appoligize for my use of the term "biweekly". By that I meant that she gets two fuzzies per week...tues and sat are the days I usually feed her. Sorry for the confusion....I haven't been able to find rat pups f/t where I go...As far as my options I have fuzzies, mice, small rats-jumbo rats. Would a full size mouse be more appropriate?
