Changing all or some of the litter tray contents daily is recommended to avoid accidents. Cats will quickly find an alternative site to use as a toilet if the tray is not cleaned daily. Let the kitten come out to explore in it's own time. Make sure there is a litter tray in the room and that the kitten knows exactly where it is. The kitten's room should also have a bowl of food and water kept a suitable distance from the litter tray.
Cats are reluctant to use a litter tray that is too close to the cat's food.
It can take days or even weeks to establish a relationship with a kitten so please be patient. Kittens need time to bond with you and before long your new kitten will become your best friend. For the first few weeks, your kitten shouldn't be allowed to roam your home unsupervised when you are not there. You should put your kitten back in their own room with their litter tray, food and water. Make sure your new kitten also has a comfortable bed or basket to sleep in with some toys to play with.
