We have recently adopted some kittens from a rescue. They are settling in well, using the litter tray etc.
No accidents - until we started letting them upstairs, within minutes of jumping up on the bed, at least one of them does a wee, could be two but not actually caught any in the act, just notice a couple of minutes later. There is also a litter tray upstairs.
Kittens are three months old.
I do not think it is a toilet training issue, dirty litter tray or stress. I think it is learnt behaviour from when they were tiny and in the rescue centre. Rescue used to request old duvets to be made into bedding. So presumably down to the Mum from when kittens were born.
So does anyone have any idea how I can break this cycle?
