Bonding most often happens between kittens or cats that are raised together. It's most common within the same litter, but it can also happen between kittens in different litters. Adult cats can also form bonds, although it usually takes longer.
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.
The average time frame is a few weeks but it could take months for the cats to learn to tolerate each other. Maintain a separate litter box and feeding area for the new cat in his room for a few weeks. It is highly recommended to have multiple resources for multiple cats.
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.
Place the cats' food bowls on opposite sides of a closed door. This will encourage them to be close together while they're doing something that makes them feel good. Each day, have the cats switch rooms so that they both experience some variation and get access to each other's scents.
Cats are family-oriented and usually live with their relatives. Cats will sleep together, share common feeding areas, and groom one another within family groups. For this reason, cats often do well adopted in pairs.
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 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.
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.
Cats that have set up separate territories in the house and don't really get along will: Chase or run away from one another and avoid contact. You may notice that one cat consistently leaves the room when one enters. Watch each other intently and may hiss or spit when they meet.
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.
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.
Most cats can at least learn to tolerate each other. But others may become so close that they snuggle together, clean each other, and chase each other around the house all day. Getting a second cat can be a blessing to your home. Just try to match the cats' personalities and make sure you set up your home for success.
The sensitive period for such learning to occur in cats is between 2 – 7 weeks of age. During this time period, owners can engineer all kinds of useful friendships between animals of the same or different species. As many owners already know, cats don't just bond to their moms or to their human owners.
After about two years of age, acceptance of another cat can be a bit random, but they will very rarely totally reject another cat in the long-term. After a time even those cats that do not become great friends can still learn to tolerate and live with each other by keeping to their own territory.
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.
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.
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.
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.
Am I giving the cat opportunities to tell me if they still want to be stroked? You can test this by following a simple 3 second rule: If you pause after 3 seconds of stroking your cat, do they try to reinitiate contact (i.e. rub against you)? If not, your cat has probably had enough for now!
Adding an unfamiliar cat to an existing cat's home can be stressful for both animals, but there are some steps you can take to help them integrate into their new home and socialize. The key is to slowly integrate new smells, give them time alone to explore their new environment and provide them with their own space.
When you think they're ready, let them mingle under your supervision. There will be hissing and growling – try to ignore it, but be ready to intervene if a physical battle breaks out. It's important to take this step slowly. If they do seem to tolerate each other, praise both cats effusively.
