How to Introduce an Older Cat to a Kitten

Introducing a new kitten to an older cat requires careful planning and preparation. Even friendly adult cats can struggle with adapting to a new kitten in the household. It’s common for older cats to display signs of sadness, reclusiveness, frequent hissing, loss of appetite, or inappropriate urination when introduced to a new kitten.

This behavior stems from cats’ dislike of change, particularly when it involves their established territory. The introduction of a new kitten can cause considerable stress in the household, but there are steps you can take to help make the process smoother.

The key to successfully introducing a new kitten to an older cat is preparation. By preparing your cat for the new arrival and making the changes seem less disruptive, you increase the likelihood that your cat will adapt to its new companion. Take your time and follow these steps to ensure a successful transition.

Relax Your Senior Cat

Pheromones are a non-invasive method to create a serene atmosphere for cats. If you’re expecting a new kitten, it’s an opportune time to utilize them. You can choose from diffusers, sprays, and wipes to help your feline feel relaxed without resorting to medication. It’s recommended to use pheromones for several weeks before the arrival of the kitten.

If you anticipate that your older cat may experience stress and anxiety due to the new kitten, you may consider using nutritional supplements specifically formulated to calm felines. These supplements don’t have sedatives, but they can assist in maintaining a calm and relaxed state. It’s best to start using them a few weeks before the expected stressful event and continue afterward. The supplements typically contain natural ingredients such as L-theanine, Phellodendron, magnolia, whey, or milk proteins, which are proven to be safe and effective for pets.

To ensure that you select a safe and effective calming supplement for your pet, consult your veterinarian, who is an excellent resource. Nowadays, there are numerous calming products available, and it’s essential to check with your vet before administering any supplement to your pet to determine if it’s beneficial and cost-effective.

Prepare your house.

Before bringing your kitten home, prepare items such as food bowls, beds, toys, and an extra litter box and place them in different locations around your home at least a week in advance. It’s a good idea to include items with the kitten’s scent on them already. Being well-prepared for the kitten’s arrival is crucial since your adult cat can sense your stress, which may negatively impact them.

Assign a small room like a bathroom where your new kitten can retreat and spend the first few days. Your older cat should be able to hear and smell the kitten from the door, but they should not interact with the kitten. Place the kitten’s necessities such as food bowls and litter boxes in this room along with a toy belonging to your older cat.

Limited access to resources can stress cats out, which includes food, water, litter boxes, prime perching spots, and you. For each cat, there should be a litter box plus an extra litter box, and these boxes should be placed in different areas throughout the house. When distributing resources, keep in mind that cats prefer not to cross paths with other cats while accessing their resources. It’s important to start using pheromones and calming supplements before making any changes in your house since this alone can cause stress-related illnesses in cats. Consult with your veterinarian for guidance on safe and effective calming supplements.

Get Your Cat Ready

Ensuring your older cat is healthy is crucial before introducing a new kitten. Added stress to an unhealthy cat may worsen their condition. Take your cat for a checkup with your veterinarian to ensure they are healthy and up to date on vaccinations. Kittens commonly carry respiratory diseases, and it’s important for your older cat’s immune system to be ready to handle any potential illness. Additionally, keeping the cats separated for 10-14 days is recommended to prevent the spread of contagious illnesses, such as upper respiratory infections.

Knowing the Feline Leukemia (FeLV) and Feline immunodeficiency virus (FIV) status of both cats is also important before introducing them. Consult with your veterinarian to determine if any testing should be done prior to the introduction.

While some older cats may immediately accept a new kitten, most require time to adjust to the changes. Some cats may never fully accept the new addition but instead coexist, avoiding the other cat in the house. It’s important to prioritize maintaining a peaceful environment, regardless of how your cat feels about the new kitten. This will give you the best chance of creating a positive relationship between the two cats from the start.

Introduce the new kitten to your cat.

When bringing the kitten home, introduce it to your older cat while the kitten is in a carrier. Then take the kitten directly to the designated room that you have set up and allow it to explore its new surroundings. Ensure that the litter box, food bowls, bed, and toys are easily accessible to the kitten. Do not allow your older cat to have immediate access to the kitten.

It is recommended to keep the kitten in its designated room with the door closed at night or whenever you are unable to supervise the kitten and your older cat. Your older cat may become curious and investigate by sticking its paw or nose under the door or listening to the kitten. You should do this for about a week, depending on how your cat is adjusting to the changes. After playing with the kitten, provide a lot of attention to your older cat and wash your hands between play sessions to avoid the spread of infections. Your older cat will need your attention and support, and the scent of the kitten on your clothing will help it become familiar with the newcomer.

Favor Spending Time Together

Once the first week has passed, it’s time to let your kitten explore the house, but keep a close eye on it while doing so. Your older cat may watch from a distance, and if it wants to retreat, let it. Don’t try to force interaction between the two cats. If your cat has a favorite interactive toy, try playing with both cats at the same time to encourage mutual activity. Treats can also be given to both cats at the same time, but be sure to leave enough space between the food bowls to avoid any conflict.

Whenever your older cat interacts positively with the kitten, use praise, treats, and physical affection to encourage this behavior. This will help your cat associate the kitten with positive experiences and increase the likelihood of a successful introduction.

Permit your cat to set boundaries

Introducing a new member into the home can disrupt the established order among cats. The older cat may try to establish boundaries with the new kitten, which can involve hissing and swatting. It is important to understand that this behavior is normal and should not be interfered with as it helps the older cat teach the kitten where its boundaries lie.

It’s important to understand that cats have unique personalities and may not become the best of friends, but they can still learn to tolerate and appreciate each other’s company. Don’t be discouraged if the initial interactions between your older cat and kitten are not positive. Introducing a new cat to an older cat takes time and patience. Rushing the process can lead to frustration and failure. Start with short supervised interactions and gradually increase the time they spend together. If your older cat is showing signs of aggression towards the kitten, seek advice from a veterinarian or a cat behavior specialist.
