A client would want me to watch her cats over break and asked if I have rates for cats
Yes you can host cats. Go in to the search (as if you were looking for a rover cat sitter) in your area for cat sitter. There is a drop down for Cats, and check to see what other hosts charge. Make sure to check if you will be house sitting in the owners home or Boarding in your home. Since this is your first time hosting a cat, don't under charge yourself but stay about average. You don't want to be raising your rates immediately or feel frustrated that it wasn't worth your time.
