What does it mean for a cat to exhibit ancestral traits?
Atavism in cats refers to a phenomenon where the expression of certain genes changes during breeding, resulting in a resemblance to their wild ancestors. This phenomenon is rare and usually occurs due to gene mutations or crossover. This means that a cat's appearance, temperament, and behavior may differ from those of common breeds. 
The manifestations of atavism in cats are highly unpredictable, especially to humans. When a cat experiences atavism, its abilities and instincts become more pronounced. It can become more intelligent, alert, and even adept at catching mice. However, some people may not like these changes because they can also mean more danger and unpredictability.
Because the chances of felines exhibiting atavism are extremely low, it can be considered a very rare phenomenon. However, a cat's maneuvering abilities, reaction speed, and ability to quickly adapt to its environment are undeniable. These are crucial for a cat's survival and hunting. Therefore, regardless of whether a cat experiences atavism, its natural instincts and inherent nature should be given sufficient attention and respect.
