Jinxi has come in as she was not getting on with the other cat in the home. She is a sweet natured girl, who now she is by herself, is showing her true character.
Jinxi will need to be the only pet in the home, so she can have all the attention. She will want eventual access to the outdoors, once she has settled into her new home.
Just like dogs it is important to introduce your new cat slowly into its new environment. Choose a safe place that is traffic free to initially settle them in and provide plenty of toys for them to play and chase. Providing a scratch mat or post will help discourage them from doing so on your furniture. Until the cat has settled it is important that the cat is kept indoors for a number of weeks. This along with grooming and interactive play will help develop your bond and ensure the cat is happy and settled in its new home.
