 Carnivore has a `bite` method, which takes a 
 herbivore object and decreases the object's health by 50. The method 
 does not work if it is another сarnivore, or the herbivore is currently hiding.

 ```python
 lion = Carnivore("Lion King")
 rabbit = Herbivore("Susan")
 rabbit.health == 100
-lion.bite(rabbit)

 rabbit.health == 50  # bited
 
 rabbit.hide()
-lion.bite(rabbit)

 rabbit.health == 50  # lion cannot bite hidden rabbit
 
 rabbit.hide()
-lion.bite(rabbit)
