Doing the best job you can for your clients (and their pets) will probably leave you with lots of warm, fuzzy feelings. First, you'll know you've provided some great TLC for the pet and peace of mind for your client. The financial rewards are attractive, too, especially if you've built up a nice client list through good service and referral business. But your best reward is visiting with friendly dogs and cats. The experience somehow blunts all the garbage that lurks in the rest of your life. Think about Fido's frantically wagging tail and all-over wriggles of joy when you arrive for a visit, or perhaps Fluffy's 90-decibel purr as he curls into your lap for a petting session. Now you remember why you wanted to be a pet sitter.
