does anyone have a suggestion as to an automatic litter tray. I have a princess who refuses to use the trays we have (3 large, covered) after they've been used by her brother (who incidentally appears to play 'use all the trays in the house within 10 minutes of mum leaving) so I keep coming home from work to a puddle somewhere where he's used the trays and so she won't and instead pees somewhere to show me her distaste.
Litter robot's seem to be the 'in' ones, but the price tag is eye watering (black friday deals perhaps??) anyone got an alternative?
