1. A cat that has just arrived in a new environment. When a cat first arrives in a new environment, it will be frightened and want to go back to its original place, so it is best to lock the cat up for a period of time to let it adapt.

2. Sick cats. Some cats with skin diseases are best kept in a cage to facilitate medical treatment and to avoid infection. Especially in households with multiple cats, they must be isolated. ​​​​​​

3. Kitten. Newly born kittens should be raised with the mother cat if they are cared for by the mother cat. If there is no mother cat to take care of, it is best to lock it up in a cage when the owner is away to prevent it from crawling around and getting lost.

4. A cat that pees randomly. If your cat has the habit of peeing frequently, you can lock it in a cat cage so that it can only go to the toilet in the litter box to improve the bad habit.
