Our ONE-PET membership is a fully functional, FREE account. This is to help out new pet owners who are starting out with one pet, possibly a rescue, and they need to set up a great staycation for their loved one while out of town. A ONE-PET member can also use this membership even if they don't have a pet of their own, but get invited by a friend or family member who needs a sitter. If you love how Petstaycay.com works, you can always move up to the premium ALL-PETS membership for a very reasonable subscription price.
