She is nearly 6, home 10 months, toilet trained day and night. She didn't even tell me she'd done it - I went into the downstairs toilet to empty the bin and found the floor wet. I asked her if she'd had an accident, she said yes. Then I realised it was only wet around the litter tray, and the litter tray had waaaay more pee than the cat could do in it. She admits she peed in the litter tray, but says she 'doesn't know why'. She must have done it while I was in the shower earlier. I'm really getting scared she is very disturbed. I've sent DCs out in the garden to play, so I can calm down. Help!
