If you raise a second cat, the first cat will be jealous. The first cat will think that the owner doesn't like it anymore, and will feel that it has been left out. It may become hostile to the second cat and become depressed. ​​​​​​

Cats don’t need social interaction, they just need territory. When you take a new cat home, be sure to isolate it and don't neglect the natives. Put the natives first in everything. Preserve everything that belongs to the aboriginal people and do not let them feel that they have been violated.
