Kitten weeing on our bed.

[Apanicaday]

We adopted two kittens a fortnight ago - they were dumped at a day old and hand reared as a result and are now 10ish weeks old. They are absolutely gorgeous little things and seem to be thriving despite their rough start to life, but one of them has taken to weeing on our bed. He did it this morning, then as soon as I opened the bedroom door this evening he was up there weeing, then I caught him preparing to go again, took him downstairs and put him in his litter tray,turned my back, and he legged it upstairs and did another one.
What can we do to help him to learn that the bed really isn't the place for weeing? His sister is really good, and although we have had a couple of accidents from her they have been few and far between and much more "accidental".

We use catsan litter in the tray, it's a fairly large one which does have a lid(but we haven't put the lid on yet as thay seemed to confuse them!) and spot clean it out as soon as we spot a poo (so multiple times a day).

Any top tips would be really gratefully received as my poor washing machine can't take many more extra duvet loads!

God. We had this with an adult rescue cat. He was Siamese and his brother never did it once. We had to throw away the mattress because once they've marked it, the smell lingers even after cleaning and they associate it with a good place for weeing.

Get some Feliway incase he's stressed and the weeing there is a symptom....and perhaps put a plastic cover on the mattress. Keep your door closed.

For now, I'd restrict access to your bedroom. Wash everything in biological washing powder/liquid as that's best for destroying smells and that might reduce the chance of your little one returning to the same spot (the smell of their own scent attracts them back).

Assuming he does it again, pick him up and say a firm no. It might help if you have an extra litter tray upstairs.

Litter tray per cat plus one. Biological washing powder is your friend. Tire them out with play and restrict access to your room. If that's not possible put a litter tray in your room for now.

Thank you for your replies! Will ban them from the bedroom for now. I've been and bought a litter tray for the bathroom and we have another so I will make sure they are around for him to use. And I will invest in feliway. They are doing really well considering, but this is a habit that I definitelt want to stop in its tracks!!!
