Fostering kittens who are not used to living indoors are more susceptible to being fearful and aggressive toward people and other cats. In addition, if you are getting a foster kitten, she will require your time and effort just like any other pet needs.
With this, kittens must be trained for socialization as soon as they reach their 4th week. It is said that training them young is easier as they haven't developed anxieties and trust issues yet. Socialization is important to help her cope with the new stage of her life.
Once your kitten is ready to live with you, place the kitten in a cage and provide her with food, water, a litter box, and bedding. Let her get comfortable and get used to her surroundings. Take it one step at a time and make sure that you don't force her to connect with you.
