No.  You are in control of the services you want to offer. If you want to stay at Pet Owner's homes, then that is an option.

• Pet Sitting is a service where you offer care for pets in your own home.
• House Sitting is where you stay over in a guest room at a Pet Owner's home to care for their pets.
• House Visits is a service where you call into an Owner's home for 15 -20 mins with a spare key you have arranged to get beforehand and you feed and water pets and clean up any messes and give them an all over body check and cuddle. You do not stay the night.
