Whether the British Shorthair can live in a cage at night depends on the specific situation of the cat. If the cat has no abnormal reactions in the cage and can quickly adapt to the cage, then it can live in the cage. If the cat keeps barking and is anxious after entering the cage , scratching and biting the cage, etc., it is best not to let it live in the cage. Generally, if a cat is used to living in a cage when he was a child, he can live in a cage when he grows up. If he has been free-range since he was a child and has never lived in a cage, it will be difficult for him to live in a cage when he grows up.
