Every time before I clean her up before bed time, I always see to it that I put her in the toilet for her to pee one last time.
Last night, I asked her to “Ok, Ysabella, Wee-wee!”
She shook her head and answered, “Low battery.”
She knows that anything that is not functioning is ‘low battery’. Apparently, even her not being able to wee-wee is low battery.
