My cat is 11yo, was born in my house and has always been inappropriate in her toilet habits. She had a litter tray before she learnt to go in the harden, which she has no problem doing when she's out there.
However, if she is in the house she simply will not go outside to pee, and will seek the nearest bed - only ever the beds - to empty her bladder. She deliberately selects beds to piss on and then saunters away so I know she CAN hold it, she just won't. This has been an issue all her life but just seems to be getting worse.
She's not sick and there have been no stressful events. We have tried reintroducing the litter tray but she's not interested. I try to keep her downstairs but some idiot always leaves a door open and she seizes her opportunity to go upstairs, find a bed to piss on and come back down.
I can't keep up with all the washing of duvets and mattresses for her to just do it again a few days later!
What can I do? Rehoming and PTS are definitely not options. I love her to bits but I simply cannot stand this vicious circle any longer!

The litter tray
Inappropriate pissing

Oh one of mine did this as a kitten (thankfully outgrew it) and another does it as a dirty protest when she's fed up so I sympathise!
Are you washing with biological washing powder?
Have you tried different cat litters? My cat who does this as a dirty protest is an absolute princess and if the cat litter I've bought isn't soft enough for her liking she'll just piss on the nice soft bed instead 
Oko is her preference.
Look out for the signs that she's about to wee, pacing and searching around, then put her into the litter tray.
Another option is to put a ssscat at the top of the stairs. It gives a harmless blast of air and will spook her enough to send her back down the stairs.
