Back from the Vet...
Milky Way has a urinary track infection which has probably caused the peeing everywhere. She also had blood sugar of 660(!) where 150 is normal, so she is mad diabetic. We got some pills and some insulin, so we will have to give her shots.
She is locked in the bathroom now. She has peed like 4 times all over the house, haha. But at least seems like is gonna be OK eventually
