You may notice your old cat hissing at a new one if you are a cat owner. Usually, they take more than seven days to stop hissing. Allow them to see each other while making a physical barrier. Remember, do not allow a new kitten to meet your cat until she stops hissing. 

Feel both the cats on the opposite side of the door; if new cats do not eat the food, keep it far away from the door so that she can feel secure to eat. Give them rewards for being calm while watching each other. If your old cat does not hiss for seven days, it is time to open the door and allow the cat to explore the home. 

Allow them to spend time with each other. There is nothing to worry about if they hassle a little by watching each other; it is normal. 

If this hissing does not die down even after 1 or 2 minutes, make the separate because it is a sign of threat. You can try it again once they both get calm.

How Do I Get My Old Cat To Stop Hissing At My New Kitten?

Most probably, your cat will be worried about the arrival of a new kitten. You can consider using calming pheromones if she does not like the new kitten. In such cases, these pheromones are very useful as they make both cats feel secure and safe. 

Remember, it is not a magical solution, so there is no guarantee that your cat will become calm. If you find no change in your cat’s behavior, you can try the following methods to spot the cat from hissing. 

  • Try Supplements 

    If pheromones are not working and your cart is still experiencing anxiety and hissing, you should consider giving them calming supplements.

    These supplements will help you to control your anxiety. We recommend you book an appointment with a vat because they will recommend the right supplement in the required quantity. 

    • Prepare Your Home

    If you are planning to bring a new kitten to your house, you should prepare your home at least a week before. Doing this will make your old cat comfortable with new supplies in the house. Also, they will get enough time to smell everything. 

    Also, make sure that all the needed things are there. Remember, do not take stress about the new cat’s arrival because your older cat will pick up your anxiety and absorb little from it. In addition, design a separate room for the new kitten so she can relax in her own space.

      How Much Hissing Is Normal When Introducing Cats?

      Some hissing is usual when they meet each other for the first time, so don’t panic. However, if this hissing does not die after two to three minutes, consider separating them because it is a sign of threat. You can try this again once the cats become calm and relaxed. 

      Usually, cats take more than a week to become normal and adapt to a new kitten. We suggest you do not leave the new kitten in front of an old cat without checking whether they hiss or not.

      Why Are The Cats Not Getting Along?

      Why Are The Cats Not Getting Along?

      Usually, both the cats do not get along because the old one does not like the change

      The harsh reality is that adult cats often have difficulty getting acclimated to having a new kitten in their home, even if they have a friendly nature. 

      Younger cats are always eager to make new friends, while on the other hand, adult cats are settled and do not make new friends frequently. As a result, the times come when there are conflicts among them. 

      You might be willing to know why your old cat starts hissing immediately after watching the new kitten. There are various reasons behind this. 

      1. They are Territorial

      Everyone knows cats are territorial creatures, meaning they cannot tolerate a new cat in their home. In most cases, the cat thinks that they are the owner of your home and that a new kitten has come to threaten it. 

      Therefore, they start hissing to protect their house from a new kitten. You must take some prevention measures and ensure their first meeting is smooth. 

      2. They Want Attention

      When a new cat comes into your home, the old ones start feeling they are not important to their owner and will get no attention from them. You have to put all the effort to prove them that it’s wrong. To ensure things, ensure you are providing them with the same treatment and stuff like toys and food.  Remember to spend enough time with both acts to entertain them so they will not get bored. Spend some extra time with the old adult cat to bring her out of anxiety and stress.

      3. She Doesn’t Like the Change

      As adult cats leave your home for longer, they have settled in their return, so they may not like the change. 

      This is why they start hissing after seeing a new cat in the home. Your cat may begin feeling misunderstood, which is essential to prove wrong immediately. 


      How Do I Stop My Cat From Hissing At My New Kitty?

      Is It Normal For The Cat To Hiss At The New Kitten?
