Cat Fighting
It can be very disappointing to bring a new cat into your household only to have the cat already in residence despise the newcomer. Most cats are quite territorial and are very happy with their current situation! However, a new cat is often needed or desired and if the first introduction is done correctly, all pets can live in harmony.
The new cat needs to be isolated in their own room for at least 2 weeks especially if there has not been a Leukemia/FIV test and fecal performed yet). Let the resident cat get used to the newcomer’s smell and sounds. Spend extra time with the resident cat, especially in front of the newcomer’s room. Spend time with the newcomer and allow their scent to get on you. Start to feed the resident cat outside door of the newcomer’s room.
When the resident cat seems content with this situation, confine him/her, and allow the newcomer to roam. Increase the amount of time gradually. Start to let the newcomer out at mealtimes, or put him/her in a crate and allow resident cat to see him/her. When all that has gone well, you can begin to let them eat in the same room, just at opposite ends. They will eventually be able to eat next to each other. The older the cats, the longer the introduction period.
Of course, there is always the exceptions: cats that can be introduced rapidly and there are no problems. However, it is safe to assume your resident cat will not appreciate a new friend. Be very cautious when adopting an adult cat from the shelter to live with another adult cat. They will get along fine if they
are introduced gradually, but you may have difficulties if they are not.
