At the Pets R Us pet store, they only have guinea pigs, parrots, cats and fish. All the pets are parrots, except 20 of them. All the pets are cats, except 21 of them. All the pets are guinea pigs, except 25 of them. All the pets are fish, except 18 of them.

Q1. How many pets does Pets R Us have?

Q2. If Adam wants to buy a cat, how many options does he have?

**Note: If your answer is 15 for Q1, and 4 for Q2, type in the SUM OF THE TWO NUMBERS, so 15 + 4 = 19. That's what you have to type.**
