Your odds of getting in are great. In fact, you should play these odds in Vegas. If your city offers a potentially profitable client base, and you can jump through the paperwork and logistics hoops, you're basically good to go. You don't need to go on a waiting list for a painfully small number of jobs, or serve a years-long apprenticeship before you sit for an impossibly grueling certification exam. Even if other pet sitters have already staked their claims in your town, you'll probably find there's room for one more player. No need for a fight-to-the-death, quick draw duel for pet sitting superiority. Many pet sitters may operate within the city limits, as they then face minimal distance between client appointments. Meanwhile, more distant suburban communities suffer from a woeful lack of pet sitter coverage. Find a niche you can exploit.
