Pet Buying

Is it worth buying a pet in MapleStory?
I ask because I am completely new to the game. I'm playing as a warrior and I just hit level 15. If i buy a pet i can not buy more than one item for it. Is it worth it?
a pet may seem like fun but becomes quite Usless after 20 days Cons: After level 11 is almost impossible to level up without having to buy more annoying things to take time to feed outside their pros day: (if you buy extra things for it) can help collect the money and when people show mesos by droping items or a drop of Styles Cool game / impress people I hope this clears up XMapleCrazyX Sincerely
