I guess your parents should have said the same thing about you. I mean you were free right? Why pay medical bills to birth you? Why pay money to buy meds when your sick or even take you to a doctor, dentist, etc?
Same goes for the family dog or cat? Your treating this pet of yours as an investment like a car, but it's not. It's a living, breathing creature who deserves a better owner than yourself. Even though you won't listen to a word we say, atleast do future animals a favor and never own a pet again.
