Taking care of a Golden Retriever while exploring the French countryside? Snuggling with a cat on the tropical island of Penang, Malaysia? When other people go on vacation, they sometimes need someone to watch over their pets—and if you fill that role, you can stay for free. 
It’s just another thing that the web has made easier to arrange. For a membership fee, several sites help matchmake pet owners with petsitters looking for free accommodation as they travel. Most of the time, the money saved on lodging with a single booking will make up for the membership cost.
The arrangement isn’t ideal for travelers who want to sightsee all day or who want to plan overnight getaways here and there, but for vacationers looking to stay in the same spot and live like a local for a short time, it can work well.
But be careful: There are pros and cons to each of the most popular housesitting and petsitting sites out there. Nearly all of them have options that allow you to filter searches by location, length of stay, and type of animal. Most will also send daily email alerts for new opportunities. As for the rest, the choice depends on what suits your needs.
