Signs of conflict between cats can be open or silent. Signs of open conflict are easy to recognize; the cats may stalk each other, hiss, and turn sideways with legs straight and hair standing on end up to make themselves look larger. If neither backs down, the displays may increase to swatting, wrestling, and biting.
If your cats flatten their ears, hold their ears back, or puff up their fur or tails, this is a sign that they're fighting, not playing. Defensive, puffy postures and leaning away from each other while hissing with bared teeth are signs that your cats feel threatened and aren't having fun.
Cats are a territorial species. While some cats overlap their territories a great deal, others prefer to keep a good distance from their neighbors. Two unrelated males or two unrelated females may have a particularly hard time sharing space. Another cause of strife may be a feline personality clash.
If your cat doesn't like other cats coming into their space and they become anxious or aggressive when this happens, this could be a sign that they wouldn't accept sharing their home with another cat. Some breeds are best suited to being only-cats, such as Bengals.
It takes most cats eight to 12 months to develop a friendship with a new cat. Although some cats certainly become close friends, others never do. Many cats who don't become buddies learn to avoid each other, but some cats fight when introduced and continue to do so until one of the cats must be re-homed.
Again, some hissing when they see each other is normal so don't be alarmed. Some light swatting is also common. Separate them if the hissing doesn't die down after 1 or 2 minutes or if there is any sign of threat (swatting with force, chasing, screaming, ears flattened, etc.). Try again when the cats seem to be calm.
Introducing too quickly with little preparation will often lead to cats feeling threatened and scared, which increases the chance of aggressive behaviour being shown. Once cats feel this way about each other, it can be extremely difficult to change their minds.
If you have more than one cat it can be very distressing when your cats fight, but it's not that unusual for them to fall out from time to time. Pet cats have evolved from a largely independent species that likes to be alone so they're unlikely to live together in perfect harmony all the time.
Simple dominance will be exhibited by a cat by marking or spraying urine on territory, stealing and hoarding toys, rubbing its face on items it wants to claim as its own, claiming specific areas to sleep, pushing other cats away from the food bowl, and/or starting at or physically intimidating other cats.
They will usually try to avoid each other if a friendship doesn't develop, but sometimes fights break out and, unfortunately, persist until one cat has to be re-homed. Two males, two females, or even a male-female pair can get along as long as they are introduced at a young age.
Don't be alarmed by hissing or growling. These are normal reactions. Encourage interaction through the door. Place your new cat's food near the door of his room so he stays near it.
Signs that your new cat is comfortable with its new environment include: Friendly behaviours when you enter the room such as approach, rubbing around your legs, chirruping, purring and meowing. Resting on its side with belly exposed and rolling over. Playing with its toys.
Cats are solitary, territorial creatures by nature so don't force siblings together. It may take weeks or months for a cat to adjust to their new lifestyle. Cats introduced too quickly may fight and never learn to get along. Gradual introductions are essential for long-term brotherly/sisterly love.
Pairs are Happier
Despite their independent natures, cats are social creatures that need companionship to thrive. Left alone, a cat can develop behavioral problems, and in some cases, even show signs of depression. Cats in bonded pairs, on the other hand, are more likely to be better adjusted.
If you have multiple cats, they may be comfortable enough with each other to share the same litter box. However, there are several reasons, including territorial behavior, why some experts would advise at least one extra litter box in your home.
Unfamiliar cats coming into the home (whether you encourage them to come in or not) can be very stressful for your cat, because they may feel as though they have to be constantly on the look-out, ready to defend their core territory at any minute.
Go slow and introduce them. For both animals this can be a stressful time. A gradual introduction process is important for them to build a friendship. If one cat gets hissed at or swatted, she may always be afraid of the other cat.
By having both cats experience something positive (a meal or yummy snack) while they are nearby, they can learn to form positive associations with each other. If either cat is growling or hissing at the other through the door, donot put them together anytime soon; take things very slowly and continue feeding this way.
Gender. Male (neutered) cats are generally believed to be more accepting of other cats, both male and female. Even though this has not been my experience, female cats may not get along as well with each other.
If you have a young cat at home and want a second, consider adopting one kitten of the opposite sex, as same-sex cats are much more prone to fight each other for dominance. Your resident cat will still be young enough to recall having fun with her littermates, and the new kitten will be more than happy to oblige.
If you're wondering if your cats will ever get along again, the answer is they likely will. They just need a little intervention on your part to help them create a purrrfect truce. Giving them their own territory and reintroducing them to each other can help bring peace back to your home.
Can Cats Get Jealous of Other Cats? Jealousy over the presence of another cat is very common. All cats have different personalities, and some will be made insecure and display jealousy more easily than others. It is important to watch your cat and observe their cues and triggers.
