which of these pets would you like to buy: a cat, a goldfish, a snake? Write your ideas using either,neither or none

I would like to buy a lot of different pets, but I haven't any money to do it. So I'll have to chose something one. For example I may buy either of cat and snake. Snake is expensive so I can take either two pets for the same price. But if I want to pick up a snake and a cat then I won't buy neither of them.
