Does anyone have a contract of care with their clients?

I am new to rover and I wanted to make a vet authorization form and also a contract with clients just in case if their pet destroys something in my home. My last pet destroyed 5 of my own pet toys, a dog bed and a few of my own items in my living room and the clients didn't pay or try to replace the items when I showed them. If anyone can email a copy of the ones they use I would appreciate it since I don't know how to start one. Thank you!
