ok here is my dilemma

i was feeding my rtb once a week a large rat, she was doing fine, it wasnt leaving a lump(i know it doesnt have to leave a lump)

so the last week of july i couldnt find any rats in my usual places, so i bought her a small rabbit she did fine with it it left a lump , but the lump was there for 3 weeks and then she pooped..... i know its not good for a lump to be there that long....

i mentioned it to a breeder friend and he suggested i feed her on large rat a month and she will do fine.

so im wondering does anyone else feed one large rat a month?

or should i stick with feeding once a week?

next time i will buy 2 mediums
