Pet's info: Cat | American Shorthair | Male | neutered | 8 lbs
I have 3 cats 18 months old, I brought another one home 26 months old fem. The 2 orange brother and sister cats hiss and chase the new cat who is a smaller short hair and she will hide under the bed. My other cat which is a short hair female about the same size get along play together. I have been keeping the new cat in my room and switching her out with the other 3 every couple days and putting the new cat in a different room. Is there a way I can get the 2 orange cats to except the new cat?

Unfortunately it's going to take time. That said, there are a few things you can make sure of to help reduce stress, especially in a four-cat household (which is a lot!). Making sure each cat has their own space where they can eat, drink, play, observe, etc without the other cats bothering them can help reduce territorial disputes over these items. Pheromone collars and plug-ins (Feliway) can also be placed on stressed out individuals, or in shared rooms (since everyone seems to be stressed) to help reduce inter-cat aggression. Making sure to have at least one litter box per cat will also help reduce stress and competition over them, and reduce the chances of accidents elsewhere. Otherwise, continued slow introduction of the cats is best. If anyone starts to get agitated or too excited, removing them to let everyone calm down and settle back in is best. Continued aggression and upset may also need a trainer or veterinary behaviorist's help. That said, if your home is very small, four cats may just be too much for everyone to get comfortable.
