Cats are clean animals, but the habit of using a fixed toileting place requires consistent training. During training, place a litter box next to the cat’s bed filled with 3-4 cm thick sand, and sprinkle a bit of sand that carries the scent of kitten urine or feces on top. When the cat becomes anxious and restless, circling around, guide it to the litter box to sniff the sand's scent, which encourages it to relieve itself there. After several training sessions, the habit can be developed. If the cat urinates or defecates elsewhere, avoid scolding or corporal punishment. Instead, gently place the kitten's head onto the excrement, show it, and say "go here to potty." Repeating this several times can correct the behavior of soiling in inappropriate places.

　　In urban settings, it is ideal to train cats to use a flushing toilet for both urination and defecation. Before training, place a plastic or wooden board under the toilet seat ring, and cover the board with an appropriate amount of sand, ash, sawdust, or other bedding materials. When the cat is seen pacing anxiously, bring it to the flushing toilet; soon, it will relieve itself there. Once the cat establishes the habit of using the board, gradually reduce the bedding amount until the cat gets used to standing on the toilet seat ring to eliminate waste, at which point the board can be removed. During training, it’s best for humans to avoid using the toilet, and the bedding should be replaced regularly, ideally once a day.

　　Some cats frequently spray urine on walls, clothes, refrigerators, stereos, bookshelves, their owner’s bed, kitchen utensils, and so on. This is a marking behavior. Unneutered cats exhibit this behavior more severely than neutered cats. To correct this abnormal behavior, the following measures can be taken:

　　1. Have a veterinarian perform neutering surgery on the cat. After neutering, the cat’s urine spraying behavior can cease or be significantly reduced. Neutering also prevents normal cats from developing spraying behavior.

　　2. Feed the cat where it usually sprays urine. Since cats are clean animals, they generally avoid spraying urine where they eat. Therefore, this method can correct the abnormal spraying behavior.

　　3. Place several mouse traps upside down at spots where the cat sprays urine.

　　4. Use a water spray to punish the cat’s abnormal behavior. Whenever the owner finds the cat spraying urine, immediately spray it with water. Over time, this can correct the abnormal behavior.

　　5. Inject progesterone. Medroxyprogesterone can be administered subcutaneously or intramuscularly, once daily at 10-20 mg per kilogram of body weight, continuously for one month.
