I have 4 cats, all similar ages - around 9. One male cat has in the last month started wearing outside the litter box - I caught him weeing on a rug and had to hire a carpet cleaner to get the smell out of the carpets and had to throw the rug. He's now done it again on one of the children's beds - he must have crawled under the duvet to do it as honestly I didn't see that the duvet was all messed up and out of place IYSWIM
Thing is whilst I had been out all day for work - which isn't unusual - I let him out when I got home for about 20 mins - he's pretty much a house cat these days since a lot of new cats moved into the neighbourhood last year - there are several litter boxes which I changed the other day he could use
I'm just not sure why he's suddenly started doing it - ive never had this problem before?
