The arrival of a new cat in your home is a huge event for your resident feline, who suddenly sees a stranger in their territory. But don&#8217;t despair! A properly organised introduction process can turn potential adversaries into the best of friends.

Unlike dogs, who are pack animals, cats are naturally <strong>solitary and territorial predators<\/strong>. Their territory is their fortress, where everything is familiar, safe, and smells &#8220;theirs.&#8221;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Territoriality:<\/strong> Your home isn&#8217;t just walls to your cat; it&#8217;s a clearly marked map of resources: sleeping spots, food, water, litter trays, and play areas. The appearance of a competitor for these resources is perceived as a threat to their very existence.<\/li>\n\n\n\n<li><strong>Scent is their &#8216;passport&#8217;:<\/strong> For cats, scent is the primary identifier. A new cat brings a million unknown and potentially dangerous smells. Imagine if a stranger suddenly walked into your home and started touching everything \u2013 a bit unsettling, wouldn&#8217;t you say?<\/li>\n\n\n\n<li><strong>Hierarchy:<\/strong> Even if cats eventually get along, they need time to establish a social hierarchy. This process is rarely instantaneous.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Our goal isn&#8217;t to force them to love each other overnight, but to create conditions where the <strong>new cat in the house<\/strong> isn&#8217;t perceived as a threat, but as something new and perhaps even interesting. We&#8217;ll proceed slowly, methodically, and with respect for the feelings of both animals.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Stage 0: Preparing for the Newcomer&#8217;s Arrival<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The ideal introduction begins even before the new cat steps paw into your home. Proper preparation accounts for 50% of success.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Your Preparation Checklist:<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Create a &#8216;quarantine room&#8217;.<\/strong> This should be a separate space (bedroom, office, even a bathroom) that your resident cat cannot access. This room will serve as a temporary refuge for the newcomer for the first few days or weeks.<\/li>\n\n\n\n<li><strong>Equip the newcomer&#8217;s room.<\/strong> It absolutely must have:\n<ul class=\"wp-block-list\">\n<li>A separate litter tray.<\/li>\n\n\n\n<li>Separate food and water bowls.<\/li>\n\n\n\n<li>A comfy sleeping spot (bed, box with soft bedding).<\/li>\n\n\n\n<li>A scratching post.<\/li>\n\n\n\n<li>A few toys.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Check their health.<\/strong> Before introductions, ensure both cats are healthy, vaccinated, and treated for parasites. A vet visit for the newcomer is mandatory.<\/li>\n\n\n\n<li><strong>Use pheromones.<\/strong> Adaptogen diffusers (like Feliway) can help reduce overall stress levels in the home. Plug one diffuser into the &#8216;quarantine room&#8217; and another in your resident cat&#8217;s territory a few days before the newcomer arrives.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Step-by-Step Guide: How to Safely Introduce Cats<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The golden rule is: don&#8217;t rush it. Each stage can last from a few days to several weeks. Only move on to the next step when you&#8217;re confident that both cats are comfortable at the current stage.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"684\" src=\"https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-1024x684.jpg\" alt=\"\" class=\"wp-image-21418\" srcset=\"https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-1024x684.jpg 1024w, https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-300x200.jpg 300w, https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-768x513.jpg 768w, https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-330x220.jpg 330w, https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-420x280.jpg 420w, https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-615x410.jpg 615w, https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315-860x574.jpg 860w, https:\/\/cdn.tvaryny.com\/wp-content\/uploads\/2025\/07\/pexels-arina-krasnikova-7726315.jpg 1279w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Stage 1: Full Isolation and Scent Introduction (2-7 days)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">1. <strong>Bring the newcomer home<\/strong> and immediately take them to the prepared &#8216;quarantine room&#8217;. Do not let the cats see each other.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. <strong>Allow the newcomer to settle in.<\/strong> They need to get used to the new place, its sounds, and smells. Spend time with them, play, and speak in a gentle voice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3. <strong>Begin scent swapping.<\/strong> This is a crucial step. Take two clean socks or cloths. Gently rub one on your resident cat&#8217;s cheeks and neck (where &#8216;friendly&#8217; pheromones are released), and the other on the new cat. Place the &#8216;resident cat&#8217;s sock&#8217; in the newcomer&#8217;s room, and the &#8216;newcomer&#8217;s sock&#8217; in the resident cat&#8217;s territory, for instance, near their food bowl.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4. <strong>Observe their reactions.<\/strong> A slight hiss or cautious sniff is normal. Bad signs include strong aggression, growling, or attempting to attack the &#8216;sock&#8217;. If the reaction is negative, continue scent swapping daily until the cats no longer react hostilely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Stage 2: Doorway Introduction and Territory Exploration (3-10 days)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">1. <strong>Feeding by the door.<\/strong> Start feeding both cats by the closed door separating them. Initially, place the bowls 1-2 metres away from the door. Gradually, with each feeding, move the bowls closer to the door. The goal is to create an association: &#8220;smell of the other cat = pleasant event (food)&#8221;.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. <strong>Territory swapping.<\/strong> Once the cats are calmly eating by the door, you can arrange &#8220;excursions&#8221;. Close your resident cat in the newcomer&#8217;s room, and allow the newcomer to explore the rest of the house for 15-30 minutes. Then swap them back. This allows them to investigate each other&#8217;s scents throughout the house in a calm environment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Stage 3: First Visual Contact (2-7 days)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">1. <strong>Use a barrier.<\/strong> The best method is to install a baby gate in the doorway or simply crack the door open a few centimetres, blocking it with something heavy so the cats can see and smell each other but can&#8217;t reach out with a paw.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. <strong>Create positive associations.<\/strong> During the first visual contacts, engage the cats with something pleasant. Play with each one&#8217;s favourite toy, give them treats. The first session should last no more than 5 minutes. If the <strong>cats hiss at each other<\/strong> but don&#8217;t attempt to attack, that&#8217;s within the normal range. Distract them with a toy and end the session on a positive note.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3. <strong>Gradually increase time.<\/strong> Once short meetings are calm, slowly increase their duration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Stage 4: First Supervised Joint Meetings (individual duration)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is the most crucial stage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1. <strong>First meeting without a barrier.<\/strong> Remove the gate or fully open the door. It&#8217;s best to do this before feeding, when the cats are a little hungry and focused on food. Place bowls at different ends of the room.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. <strong>Be present and calm.<\/strong> Your nervousness transfers to the animals. Speak to them calmly, but don&#8217;t try to stroke them or pick them up at this moment. Have a large towel or piece of cardboard handy to safely separate the cats in case of a fight.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3. <strong>Keep meetings short.<\/strong> The first meeting might last 10-15 minutes. End it before signs of tension appear. It&#8217;s better to finish early on a good note than to wait for a conflict.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4. <strong>Repeat and increase time.<\/strong> Repeat these controlled meetings several times a day, gradually increasing their duration. The process of <strong>how to make cats friends<\/strong> can take a considerable amount of time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Something Gone Wrong?
