Bin expansion = change behavior

So before in my hedgehogs old bin, she used to jsut be content to running on her wheel and using her litterbox to poop. Now, since my girlfriend and I have expanded the bin by connecting a bin of the same size, she doesnt poop in her litterbox anymore and exclusively poops in her wheel. Now she just uses the litterbox as a sandbox (she likes to roll around in it and dig in it). She even stopped sleeping in her pipe, now prefering the corner of the new bin that we connected. On top of this, she makes a mess now in her new bin, burrowing EVERYWHERE.

i guess before she needed a designated play bin haha
