Stressed out cat after a move? Advice appreciated!

[regnamechange]

We moved house the week before Christmas, our 3 year old tom cat settled very well in the new house and was using the litter tray ( we were worried he wouldn't as has gone outside since he was a kitten) After a week and a half we let him out once or twice (went out with him) and then few days later he went off exploring, we then took the tray away again. He has since come back each time he has been called etc. This last week however he keeps weeing on my sons bed. Its driving me insane! Especially as he has been out most of the day!
I am going to start closing the bedroom doors any more advice would be much appreciated as I am getting at the end of my tether now!!

My vet advised us to get a Feliway plug-in - maybe try that? I think you can get them on Amazon as well as from the vet

Feliway is good, plus there is always the possibility he wandered into another Mog's turf and got sent packing?

There seems to be a fair few cats around here but so far no fights, which was a regular occurence in our last home ( he is a fairly big cat! ). We even caught him weeing in our garden so we were foolishly thinking that we were breaking on to the next step of settledom!

Off to check out the link, thankyou!
