Most cats have very good litterbox habits.
But sometimes even the most faithful of litterbox users may have accidents. Sharing a house with a cat who eliminates inappropriately can be very frustrating. Understanding why the cat is not using the litterbox is the key to solving the problem, along with good measures of patience and persistence. If your cat is having litterbox problems, the first step is to take him to the veterinarian for a complete health examination. If the problem is medical, the veterinarian will probably prescribe antibiotics and possibly modify the cat's diet.
