Take your kitten to its kitty litter box right you bring it home. Sometimes that first visit is all is necessary. But until you're sure that the kitten understands, take it there after each feeding. Sometimes felines will not use a kitty litter box if something about the particular make of litter is not to their liking. Occasionally they will stay away from the box if its location is not private enough. Try to solve these problems if the kitten will not use the litter box from the start.
Next, ensure that the kitten is neither too skinny nor too excess fat. A kitten that is either all skin and bone fragments or has a bloated abdominal will probably have contamination. Do not select such a kitten. Also check the kitten's nasal area and ears for just about any sign of discharge or infection.When you are checking for signs of physical health, take note of the kitten's personality. Hold the kitten to another area of the room and watch how it behaves. Could it be nervous or scared? Does it respond to soothing petting by growing calmer? You want a kitten that changes quickly to you. This is a sign it's been handled by the owners of the litter, which is important in setting up the kitten for living with people.
