I have been writing to you about my Maine Coon Cat 2 years

This answer was rated:

I have been writing to you about my Maine Coon Cat 2 years old, Male. We recently brought a new 5 year old Maine Coon Cat Male into the house and my cat will not accept this new cat. The new cat is so sweet and easy going while mine is very spoiled and quite honory but he is my baby and I want them both to be happy. At first we thought they were going to get along but now my cat does not want the new cat anywhere near him and the new cat is starting to hide. The new cat seems to try to get along with my cat but lately to no avail. They have been together about a month now. I have been using Feliway and it is not helping.
Welcome to JustAnswer! I am a licensed veterinarian and would be glad to help!

Are they hissing?


How many litterboxes are in the house?

Customer: replied 7 years ago.
There is some hissing and now some fighting. The actual fighting is new. There are two litter boxes in the house but the new cat was occasionally using my cats litter box. Now he won't even come downstairs to my apartment at all. His litter box it upstairs in my daughter's apartment and now is using his own litter box.
While I certainly undertsand you are concerned, this is quite normal behaior when a new cat is brought into the house.

When we have problems such as this, there are several options to consider - often trying to give them a short break from each other and go back to the revert back to before the interaction started to re-train them.

1) Place the cats in separate rooms (different litter, food, and water) for a period of time, often at least 3-5 days.

2) During this time, allow each cat to play with a blanket or toy.

3) After a few days, switch the blankets/toys - this will give the other cat a sense of smell / scent of the other cat.

4) After a few days, you can also allow each cat to see or smell each other under a door or through a gate to get used to each other.

Hopefully once a week or 2 passes with these recommendations - they get used to each other, they will be great together!

Most are...but I know it is sometimes hard to watch them get to know each other over the first week...

Moreover, changing the environment in these cases can be helpful.

Often this revolves around enrichment in the environment - giving them activity that is positive, rather than negative - often distracting as well, so they are not focused as much on each other.

Examples include
- Self-Play Toys

- Interactive Toys
- Videos designed for cats
