Cats are born to be clean and are aware to keep their little box clean all the time. So what each cat owner needs to do is to buy a litter box big enough for the kitten to move around in and fill the bottom of the tray with enough litter.
Accidents would occur even for those smartest kittens. Try not to punish your kitten whatever they do, you can learn to praise her with a small reward, like a kibble of her favorite kitten food.
Keep in mind the number of little box should be more than the number of cats in the house. For instance, a two-cat household should have three litter boxes to keep accessibility. Once your kitten arrives in her new home, immediately show her the location of the little boxes. Look at your kitten carefully at first and make sure she enters into the box after meals. If you see her sniffing around, which is one of the signals she needs to go.
Litter box dos and don’ts
Locate litter boxes in quiet locations that are easy for your kitten to reach rather than near any noisy appliances.
Put your kitten’s litter box away from her bed in a private location.
Clean the box regularly.
Scoop out your kitten’s litter boxes every day and change the litter when needed
Never use disinfectants and bleach to clean the litter box as some disinfectants are toxic to cats. It’s best to use hot water and detergent, which contain no harmful substances.
Don’t clean the litter box when you are pregnant. If you must clean the litter box yourself, make sure to wear rubber gloves and wash your hands thoroughly after cleaning the box. Thoroughly cleanse should be done daily, which can minimize the risk of toxoplasmosis.
