Welcoming a new cat to the family is exciting for humans, but not always for resident cats. While some cats get along immediately, others need time to adjust. It's normal for cats to hiss when they first meet, as hissing is a form of communication. Read on to learn more about why cats hiss and how to help them get along.
How Much Hissing Should Be Expected When Introducing Cats?
Hissing is normal when introducing cats. They may hiss or swat at each other for weeks as they get to know each other. Hissing on its own isn't aggressive, but if accompanied by other aggressive behaviors, intervention is needed. Growling, hair standing on end, tense muscles, and pinned ears may indicate aggression.
Why Do New Cats Hiss at Each Other?
1. Their Routine Is Disrupted
Resident cats are creatures of habit and don't like change. New additions can make them anxious, stressed, and confused. They may need more attention when a new pet arrives.
2. They Feel Trapped
Rushing introductions can make both cats feel trapped. Resident cats need time to get used to sharing space, and new cats are already stressed in a new home. Don't block exits and let them interact on their own time.
3. They Feel Their Space Is Being Encroached Upon
Resident cats may hiss because they feel their space is being invaded. Hissing can establish or reinforce the social hierarchy among cats. Dominant cats may also engage in other territorial behaviors.
4. They're Setting Boundaries
Cats are territorial and hiss to establish boundaries and authority. A hiss is a quick way to tell a newcomer to stop trespassing.
What Should I Do if My Cats Are Hissing at Each Other?
If hissing persists, there are steps you can take.
Sit It Out
Hissing is a form of communication. If it's constant, separate the cats and let them calm down. Intervene if there are aggressive behaviors.
Introduce Them Slowly
Introductions should be slow and deliberate. Let the more fearful cat set the pace. The process can take days, weeks, or months.
Don't Be Afraid to Do Reintroductions
If introductions were rushed and cats are fighting, separate them and start over.
Provide Enough Resources
Aggression can result from cats feeling they have to share resources. Ensure each cat has its own litter box, food bowl, toys, scratching posts, and sleeping spots.
Final Thoughts
Hissing is normal during cat introductions. Cats need time to adjust to new situations. Introduce new cats slowly and let them set the pace. Don't rush the process.
