Just i am not keeping her in cage ..she is 24h out and now she use her old cage as toilet ( which means cleaninggggggggg alottt ) About food- i dont know if ur giving her other vegy and this food for them ( i got it in some so called animal shop in Mushereb ) - maybe diferent kinds of food will make her more happy and will less eat... as advice for wasting extra energy coz it looks like she has it lot :) try to play with her while she is in flat free ...and ran... mine is running like- kitchen-bedroom-balcony-living room- hall
