Saving Penny! !! !!

I was hit with an unexpected mandatory 300 dollar pet deposit from my apartment. I have until the 21st to pay it or I have to part with my little furry baby Penny.  I've already tried to talk myself into maybe giving her up. Biggest mistake of my life I cried for an hour and a half non stop I couldn't do it. I'm doing everything in my power to raise this money. IE: odd jobs, baby sitting, dog sitting, bike delivery and I'm really just trying to get as close as possible to this 300 dollars. Everything helps could be a dollar or even five. I really appreciate any thing you can give.
