This:You might want to try a water flosser. I wear a permanent bridge and the water flosser gets everything out from under it that the little brushed never could get. You can get a good Waterpic one for under $40 from amazon.
I haven't checked in here for a while so I bite: what's a Princess Palace besides that Disney junk all the little girls appear to be crazy about? Some kind of pet confinement as it seems to be something you can take outside for small animals??
because Willow is a spoiled wotten widda pwincess and it's positively palatial compared to a regular cat carrier.
She isn't going to live in it full time, of course, but if they're set up right a cat almost could.
