OO Inheritance

Object Oriented Programming Inheritance. Is there even a point to it? Every time I see people try to explain it they always use that fucking "Animal", "Dog", "Cat" example. I'm honestly not seeing the benefits here. Can someone give me a practical example?

i have likewise come to the conclusion that classic inheritance is mostly awful...

lately i have been interested in "traits", a way of composing behaviour without having to have one specific ancestor:

i'm not certain yet, but it seems like a more useful way of structuring things.
