I have the most cosseted cat EVER-scratch posts in every room, a huge cat tree, microchip cat flap so free access. He's cuddled, adored and played with but he's spraying 
I've seen him spray in the garden against the bushes and I've posted about him spraying when I was sorting out my cupboards and I think he got unsettled. Understandable.
Last night he was playing and purring and generally being delightful and suddenly sprayed against the wall!! No sign of being spooked or another cat near by so I don't understand what's going on.
He seems completely fine in himself.
I've ordered Feliway,Pet Odour destroyer spray and a UV light to see if he's been busy any where else.
What else can I do? I'm reluctant to get the calming capsules as I've read reviews about making the cat feel poorly.
Any other suggestions?
