    They need a space that feels like their own to get comfortable. Make sure your older cat can’t get in, and set up food, water, and a litter box for your kitten. Keep them confined in the room when you first bring them home, and supervise any time they spend outside of it. It will help them feel comfortable and safe in their own space. [1]

    It might not seem like it at first, but cats can get used to each other (and even learn to love each other). The most important factor is going slowly and paying attention to what your older cat needs along the way. Every cat is different, and your cat might need more time to get used to a kitten than other cats do. [2]

    Grab a blanket that the kitten has slept on and put it near your older cat’s food dish. Let them sniff it and smell it for a few days before you introduce the cats to each other. Your cat will be better prepared for the new kitten if they’ve smelled them first. [3]

    Put up a baby gate or a mesh screen and let your cats look at each other through it. Don’t allow contact just yet—instead, let them sniff each other and meow if they’d like to. Keep the interactions short (a few minutes is fine), and try to end them on a positive note. Do this a few times over a few days until your cats seem like they’re getting along. [4]

    "When we introduced our new kitten to our resident cat, we used a mesh screen door made by QWR and it was perfect. You just attach it over the door to your kitten's "base camp" with the built-in adhesive backing and Velcro strips, then use the zipper to open the mesh screen door anytime you need to get in or out.

    The mesh screen allowed our cats to see and smell each other without making physical contact, which was super important since we wanted to take things slow and avoid any altercations. We preferred this over using a baby gate since cats are still able to jump over gates and stick their paws through the bars."

  2. 2
    Supervise their initial contact. When you feel confident that your older cat won’t attack the kitten, open the door and let them meet face to face. Stay in the room with them, and let them sniff each other if they’d like to. Keep these interactions short, too, and do them a few times a day for at least a week. [5]

    If the supervised visits are going well and your cats aren’t attacking each other, it’s probably fine to leave them alone for a bit. Start slow—leave the room for 5 minutes, then 10 minutes, then 15. If you’re leaving the house, separate the cats just in case. [6]
Question 6 of 8:

What do I do if my older cat hurts the kitten?

    Reaching into an ongoing cat fight will only get you hurt, so it’s important to do this first. You can clap, yell, or stomp to get your cats to break contact before you step in. [7]
  2. 2
    Separate the cats right away. If they’re attacking each other, the meeting isn’t going well. Put the kitten back in their separate space and let the cats have some alone time. You might need to backtrack your progress a bit—if you were letting the cats meet each other without barriers in place, try putting a gate up again and letting them sniff each other. [8]

    Every cat is different, and some might need more time than others. Some cats are fine within a few hours, while others might need a few months of short meetings. Old, temperamental cats generally need more time than young, more laid-back ones. [9]

    Some cats have a really hard time getting used to a new animal in the house. If your older cat isn’t letting up, make an appointment with your vet or talk to a certified cat trainer for help. They’ll come up with ways to make both of your cats happy so they can get along in peace. [10]
    • Older cats may show signs of stress by not eating, not using the litter box, or hiding all the time. If that’s the case, it’s time to get a professional’s opinion.

      Tips

      • Have at least one litter box per cat plus an extra one. That way, each cat has their own space to do their business. [11]
        Thanks
      • It's best to adopt 2 hyperactive kittens rather than just one. That way, they'll use up that hyperactivity on each other rather than the older cat.
