We've had Nibbles now for about 6/8 weeks. She's settled in and not bitey anymore, copes with being handled and loves running around freely when given the opportunity.
Yesterday I added a bin cage to extend her current rotastak cage. She bloody loved it and was running in her new (massive) wheel and scampering through the tubes back and forward between the two cages.
Came down this morning and she has completely blocked up the tube with bedding and my dilemma is whether to unblock it or leave her to do it when she wakes up later on.
