Как обратиться к значениям переменной одного класса из метода другого класса

class Family:
    def __init__(self):
        self.house = House()
        print('Введите имена членов семьи')
        husband = Husband(input())
        wife = Wife(input())
        cat = Cat(input())
        self.fam = [husband, wife, cat]
 
 
class House:
    money = 100
    people_food = 50
    cat_food = 30
    dirt = 0
 
 
class Animals:
    hunger = 30
    saturation_coefficient = 1
    eating = 30
 
    def __init__(self, name):
        self.name = name
 
    def eat(self, house):
        if isinstance(self, Cat):
            self.eat2(house.cat_food)
        else:
            self.eat2(house.people_food)
 
    def eat2(self, food):
        if food < self.eating:
            self.hunger += food * self.saturation_coefficient
            food -= food
        else:
            self.hunger += self.eating * self.saturation_coefficient
            food -= self.eating
 
 
class Cat(Animals):
    saturation_coefficient = 2
    eating = 10
 
 
class People(Animals):
    happiness = 100
 
class Husband(People):
    happiness = 100
 
class Wife(People):
    happiness = 100
 
 
fam = Family()
for i in fam.fam:
    if isinstance(i, Animals):
        print('Животное')
    if isinstance(i, Cat):
        print('кот')
    if isinstance(i, People):
        print('Человек')
    i.eat(fam.house)

print(fam.house.cat_food)
