Cats can be scared of many things, and some of these fears may seem irrational to humans. Here are some things that cats are commonly scared of:

• Loud noises: Cats can be scared of loud noises such as thunder, fireworks, or even household appliances like vacuum cleaners.

• Water: While not all cats are scared of water, most of them are. This may be because their ancestors were desert dwellers.

• Unfamiliar objects: Cats can be afraid of unfamiliar objects such as cucumbers, plastic bags, balloons, or fans.

• Changes in routine: Cats are creatures of habit, and they can become anxious when something takes them out of their usual territory or routine.

• Threatening or unfamiliar animals: Cats can be scared of other animals, especially if they are unfamiliar or have threatening qualities.

• Being startled: Cats can be scared by sudden movements or the sudden appearance of objects, even if they are not inherently threatening.

Its important to note that cats can hide signs of fear and anxiety very well, making it hard to pick up on their fears. If a cat is scared, it might try to hide somewhere inaccessible, get up to a safe, high vantage point, or run away. When these coping mechanisms dont work, cats may feel the need to show aggressive and confrontational behavior in an attempt to repel and create more space between themselves and the perceived threat. Its important to respect a cats boundaries and not intentionally scare them, as this can cause unnecessary stress and anxiety.
