TrustedHousesitters.com is a website that books travelers who volunteer to combine visits to homes throughout the world with caring for the family pets. If you can create travel plans to include destinations that require your services, you may earn free nights in some unique homes.

You may be spending the night with Rover in a Honolulu beach house. Or lolling with Tabby within a New York high-rise condo. Or strolling with Shep along the grassy fields of a regal English estate.

To apply, volunteers must offer proof they’re experienced in feeding and caring for the pets.  It costs $119 annually to be a member of the pet-sitting volunteer clan.
