Every animal is different. If you have an adult female cat and are looking to adopt another female, a kitten or a youngster is your safest bet. Two female kittens raised together should be fine as well.
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.
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.
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.
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.
As long as both pets are spayed or neutered, the sex of the cats doesn't matter; it's temperament and age you'll want to take into consideration.
Don't worry too much about the gender of the cats involved. Age and temperament are the most important factors. Adult cats will usually accept a new kitten much more easily than they will accept a new adult cat. Cats are territorial, and your cat may resent an adult feline intruder.
A laid-back, older (neutered) male cat may enjoy "mothering" a kitten - male or female. They usually make better mothering substitutes than spayed females. Females, in general, are less accepting of newcomers.
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.
Male cats tend to be more social and affectionate with both humans and other cats. They commonly form strong bonds with other cats in the home, even when they are not from the same litter. Females, on the other hand, are often more standoffish. If you are looking for a cuddle bug, adopting a male may be your best bet.
First – Visual contact between cats
Separate physically with screen door or baby gate. If not possible then open new cat's door slightly so cats can see each other but cannot fit through door. Give cats treats so they spend time close to each other or play with a feather to encourage play. Do not use catnip.
When resident cat approaches the blanket, observe closely the body language. Normal language would be sniffing, pawing, and even growling. Warning signs would be flattened ears, twitching tail and hissing, if you see any of these warning signs, you may be in for a bit of a battle when the two first initially meet.
Follow this simple rule: one box per cat, plus one extra. So if you have two cats, you should have three boxes. Making sure everyone has their space can help ease elimination issues. Some owners prefer a hooded box, but some cats don't like them.
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 either party appears aggressive, fearful or just unsure, don't force the interaction. Separate them again and continue with scent swapping. Cat and/or kitten may vary with their reactions; from curious to unconcerned, playful to nervous. Make sure both have plenty of space and the ability to retreat if necessary.
However, Cats Can Share Water Bowls
But, cats tend to get thirsty and drink at different times. So, it is less likely that multiple cats will try to drink at the same time from the same water bowl. There also is usually a lot more water, enough for everyone.
Having multiple boxes prevents overcrowding into one, where your cat has to step on others' waste and may feel like there's not a spot clean enough to “go.” Not finding what she needs in her litter box, she'll choose another spot where no stepping over waste is required.
Many pet owners have a shared bowl for dry food, which cats can access at any time. As cats tend to graze on dry, there is less chance of them all trying to eat from the bowl at the same time. Some cats will stick with their own food bowl, but it's not uncommon for cats to swap between bowls.
The differences between a male or female cat
Usually male cats are much more cuddly, especially after being spayed, while females are more aggressive or defensive by their maternal nature.
Two Can Be Better Than one
Cats can get territorial if they don't have enough individual space, so if your home or apartment is small or cluttered, two might not be the best choice. To avoid potential conflict between pets, try to adopt young cats at the same time.
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.
Fortunately, neutered and spayed cats are much more likely to get on well together than intact adult cats. Generally, female cats tend to be more accepting of new cats into their home. They are more likely to accept another female cat than a male cat.
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.
Cats are naturally solitary animals and are often happy without the company of their own species. They are territorial animals who don't like conflict with other cats. Introducing a new cat to an existing cat in the household takes time and patience – but don't worry, we have advice for this!
