Congrats on your new little one!!!
It's always fun to be a new mom! hehe
Search here or do a google search for introducing a new cat to an existing cat household. There is a lot of info. Most recommend that you keep the new cat separate for a period of time. The cats will sniff each other under the doors and all and there will probably be hissing. Once this eases, you can move to the next step which is letting them see each other (block a door open) so they can sniff and see each other but not get at each other. During this time it is also helpful to switch the rooms the cats are in; if the new cat is in the bedroom and the others are in the living room, reverse this for a few hours so they can smell each other without actually coming in contact with each other. The next step is to let them out together for supervised visits.
Each step is important in the process of adapting everyone to each other and the whole process can be as short as a few days to as long as a month or more. Each situation is different. Just take it slow and it will work out.
If there starts being a lot of hostility, just back off to the last step and try again.
You can never move to slow with new cat introductions but you can
move too fast.

The recommendation is really 1 box per cat +1, so for 3 cats there should be 4 boxes, but most people I know get by with the same # as there are cats. Lots of scooping, but it's better than cleaning pee from the carpet!! LOL
Looking forward to pics of your new addition!!
