Many pet owners have certainly observed some phenomena on their pets, especially cats. Sometimes their bodies emit slight tremors, which can puzzle the owners. What exactly causes this?

Cat's visual ability

First, cats' visual ability is far more powerful than humans'. Their eyes can accurately capture small movements. For example, when a fly lands on an indoor wall, a cat can quickly notice it and begin preparing to hunt. They can also spot targets far away, such as a fly flying tens of meters away. This ability causes cats' bodies to constantly tremble because their muscles are continuously adjusting the visual focal point to catch the fly's movements.

Cat's sleep state

Secondly, when cats are in a sleep state, they also exhibit slight tremors. This is their natural response because even when sleeping, their brain remains active, continuously checking for danger. Once a threat appears, they immediately sound an alarm. So during sleep, they emit slight tremors to protect themselves from harm.

Cat's hunting games

Furthermore, cats have a habit of playing hunting games. For example, they chase shadows on walls or jump up to catch things in the air. At these times, their bodies also exhibit slight tremors because their muscles constantly contract to adjust their body's posture to catch airborne targets.

Cat's attack mode

Finally, when cats discover other animals invading their territory, they also emit slight tremors. This signals they are preparing to attack. They can quickly shift postures to get ready to strike the intruder, and during this process, their bodies slightly tremble.

In summary, cats' slight body tremors stem from various reasons: their visual ability causes constant focal adjustments, they tremble slightly during sleep, they exhibit tremors during hunting games, and they also tremble slightly when facing danger to defend themselves.
