In order to understand why your cat starts to foul not in the tray , the first thing to check is not whether the cause that changed the behavior of the pet, the disease. If during urination the animal has pain, then the cat can subconsciously bind it to the tray. Therefore, initially, you should contact the veterinarian to conduct a study.
There are, however, situations where the cat deliberately damn past the tray, then the owner should carefully observe the pet and try to quickly establish the cause of such behavior. In the reasons why the cat began to shit not in the tray, we'll try to figure it out.
The reasons why the cat shits past the tray
This behavior of the cat can not be causeless, for sure the animal has a problem that he wants to draw your attention to. If such a cause as a disease is excluded, then take a closer look at the shape and size of the tray, perhaps your pet has grown, and it has become inconvenient to use it. Also, the cause can be a smell, if it is eaten into the plastic from which the tray is made, or it is simply unfairly washed away.
If the tray is all right, then why do not the cats smack in the tray? The pet may not like the smell of the filler used for the tray, or the apartment has a new smell, such as a child or other animal, repairs are made, the situation is changed, and then the cat feeling the "threat" of their territory begins to leave marks, declaring their rights.
Another reason may be the advanced age of the animal and the disorder in the nervous system, loss of control.
What should I do if the cat catches the tray? If it is associated with the disease, then, undoubtedly, treat. If the cat does not like the smell coming from the tray, then try changing the filler, or cleaning products, or the tray itself.
In any case, one should not beat and punish the animal, it is necessary to establish and eradicate the cause, or to correct its relations with it.
