i have a hide on either end and three out of the 4 sides are covered and its like a switch flipped when i put her in there she just became aggressive almost instantly within the first hour of moving her in there. and it is deffinately new bc she was never aggressive when i handled her and now she is just one pissed off little girl haha even when im holding her she doesnt calm down at all she just stays tense and she will even strike
