The first days of your kitten's life in their new home are important in building a happy relationship between your kitten and their adopted family. For that reason, it's best not to introduce your kitten to your household during particularly busy times such as holidays and birthdays. A new kitten needs a quiet environment and lots of care from their new owners - two things that can be hard to provide during the hustle and bustle of family celebrations.
When you bring your new kitten into your home for the first time, they will probably be a little apprehensive. It's best to keep your kitten in one room until they have grown accustomed to it, before opening the door to allow them to roam through the rest of your home.
Give your kitten plenty of attention and be prepared to spend time playing with them while they becomes acquainted with their new home.
