This little shit has started peeing on things such as our bed, clean clothes if left on the bed and shein packages if left on the floor, what could be causing this? His litter box gets cleaned out at least twice a week if not more and he gets fed every 6 hours like clockwork and all the love and playtime and attention he could ever ask for plus treats all the time. We have had him for 4 years and only recently has he started doing this never any problems before please help
