Most often the reason an adult cat "forgets" about the whereabouts of the tray, and starts to spoil, where got is pain. Most likely, the animal experiences suffering at the time of urination or bowel movements, and for some reason believes that the guilty in pain it is the tray. Trying to get rid of the pain, the cat tries to pee in other places and often on a cozy, soft and safe bed owners. The reason can be worms, constipation or kidney stones.
It is not excluded that the cat wasn't happy with the tray, his smell or the location. The owners should remember, did not change whether they are detergent or cat litter. If the cat is not the only one in the house, it is possible that other animals use her tray, so she avoids him.

What to do if a cat shits on the bed?
In fact, cats are really clean animals and never shitting where you eat. So you can put the bowl of food in those places where it was previously detected cat feces.
It is most logical to show the animal to the veterinarian in order to exclude the disease. It is not excluded that it will take treatment of any organic pathology, but the cat will be healthy again and stop to write in the wrong places "fragrant" markers.
