That sounds really frustrating, especially since chinchillas can be so particular about their routines. Sometimes a new dust bath bowl can feel unfamiliar or even intimidating to them, especially if the texture or shape is very different from what they’re used to. You might try placing the new bowl right next to the old one for a few days, so she can gradually get used to the new setup without losing her comfort zone entirely. Also, double-check that the dust itself hasn’t changed - some brands or batches can feel different or even irritate their sensitive skin. If she’s still not interested after a few days, maybe try gently dusting a small amount on her fur to remind her how nice it feels. Hopefully, with a bit of patience, she’ll warm up to the new bowl soon! That hesitation to use the new dust bath bowl sounds like it might be more about the change itself than the bowl or dust. Chinchillas can be surprisingly sensitive to new textures or smells, so even a fancy upgrade might feel unfamiliar or unsettling to her. Maybe try placing the old plastic bowl back alongside the new one for a few days, so she can choose and gradually get used to the new setup without pressure. Also, I once noticed my chinchilla avoided a new dust bath because it was a bit deeper than she liked - she preferred a shallower layer she could easily jump in and out of. If your new bowl is deeper or has a different shape, that might be worth experimenting with. Sometimes it just takes a little patience and letting her lead the way.
