Smoking or alcohol abuse are certainly not the case with cats, but that doesn't mean that animals don't have bad habits.
In this case, we are talking about the pet’s behavior that is harmful to its health or causes inconvenience to the owner.
The owner of the kitten, who failed to explain the meaning of the word "no", should be blamed for this habit, not the hunting instinct of the pet. But you can still try to fix the situation - when playing with the cat, use toys, not legs and hands, and if it exhibits unwanted behavior, spray it with water from a spray bottle.
Cats are famous for their cleanliness, and if for some reason they ignore the litter box, try to understand the reasons for this behavior. Perhaps the situation will change if you change the filler or move the cat toilet to another - quiet and secluded place.
Another "toilet" problem arises from the pet's passionate desire to dig in the tray before or after using it for its intended purpose. We see a way out of this situation in using a tray with high curved edges or a house-shaped structure - then the filler will not be lying around everywhere.
There are several reasons for this problem, but we will not list them. Instead, we will suggest a solution - castration of the animal, after which the cat not only loses the desire to leave marks, but also the level of aggression decreases and the desire to run away from home disappears.
