WHY ARE MY CATS FIGHTING ALL OF A SUDDEN?
If your cats start hissing and clawing out of nowhere when they used to be friends, you might find yourself wondering, "Why are my cats fighting all of a sudden?" What was once a happy friendship has now turned into bullying and flying fur. Whether they're fighting because they smell differently or got spooked, your cats probably won't stay enemies for long. Here are some reasons why your cats don't get along anymore, as well as steps to help ease them into a friendship again.
One Cat Smells Different
If one of your cats suddenly smells differently, the other cat may react pretty violently at first. This can happen if you took one of your cats to a vet or a groomer, for example.1 Cats identify each other through smell and voice, not just by sight. A weird, unfamiliar smell signals an intruder, not a friend.
Eventually, the two cats will remember each other, but it can be pretty disturbing to watch best friends fight until they figure it out. Some people schedule vet visits at the same time to avoid this.
If you can't take them to appointments together, try rubbing the returning cat with a blanket your cats sleep on before reintroducing him to the home. Another option is to lightly rub your hands with a pleasant scent, like smelly treats or water from canned tuna, and then gently pet your kitty. The distracting but pleasant scent might overpower the vet's scent.
Fear Takes Over
Sometimes cats get scared, and this causes them to misdirect their "fight or flight" response at the wrong target. This might happen if two cats are sleeping peacefully next to each other, then hear a loud noise. Both cats get scared, jump, and puff up into defensive postures. They see each other puffed up and fear the other is attacking. This could lead to unease and fighting until they figure out they're still friends.
They're Insecure about Territories
Sometimes sudden outbursts are caused by unease about territories in the home.2 Cats are naturally territorial, but friendly cats have learned to share their space peacefully. If you recently moved to a new home, they may need to work those issues out again.
Changes in your own life can also trigger territory insecurity and stress in your cats. If you recently got married, had a baby, or even changed your work schedule significantly, your cats might be feeling a little shaken up and insecure. They could easily take that stress out on each other. When a significant change takes place, try to stick to your cats' routine as much as you can, including mealtime and bedtime. Spend extra time playing with them, so they don't feel jealous. Be patient; it might take a little time to adjust.
