I often meet with cases where dog owners give birth to a cat and expecting it to behave like a dog. They very upset, when on friendly molestation their dog, cat reacts “inadequately”, is beginning to fight and hiss.
We have a long time to explain that the cat reacts is just right, but the dog is not well, and what to bring then you need a dog, not a cat. After all, if the dog will not try every hour to bite off a kitten’s tail, though it is a fun game from his point of view, the cat will not attempt to dig claws dog eyes.
Cats and dogs do not understand language of each other’s body, even though it is very similar. Over time, when the animals live together for several years, they will learn to communicate.
