The reason cats and dogs don’t get along is because of their different habits

Cats and dogs are solitary animals and social animals. Solitary animals are naturally more sensitive to the outside world, and cats are also nocturnal animals. They are used to being alone, but they are not used to it. Live with other animals.
Dogs are social animals and have a certain degree of curiosity about other animals. They like to join in the fun when they see something. Generally, dogs provoke cats. And dogs are relatively large, so cats are somewhat defensive about them. In addition, cats still have hunting habits and will usually be the first to attack.
For cats who are nocturnal animals, it is their resting time during the day, and the interruption of dogs is obviously not welcomed by cats, which is also a reason for discord.

The reason cats and dogs don’t get along is because they express different meanings

When a cat raises its tail, it means that it is showing kindness to you; and if a dog raises its tail, it means that it is showing kindness to you; It is full of hostility, so when a cat raises its tail, it is often misunderstood by dogs as a sign of hostility. Similarly, if a cat purrs, it is a pleasant invitation to be petted, and when a dog gasps, you have to stay away, because they are really angry. Therefore, when the cat huffs and puffs, the dog thinks it is angry, and a fierce fight is inevitable.
In addition, when a cat is comfortable, its throat will make a "whining" sound, which in the dog's eyes means fighting and teasing; when a cat is angry, it will arch up and move its center of gravity backwards with its tail erect, which the dog thinks is It means surrender.
Another example is "wagging the tail". Dogs mean intimacy, while cats mean fighting; dogs want to be intimate with cats, but cats think dogs are looking for trouble.
