I would not trust the care of my cat to paying AirBnB guests. It’s not just the feeding, but how they would treat her. If any issues happen then you also have to deal with a random AirBnB rep who may or may not be sympathetic or care about details of your arrangement with the guest.
If you need someone to look out for your cat while you are away, recommend to use a different platform where you can interview potential guests and handle communication and payment **directly**. I just don’t think AirBnB mixes well with pet sitting.
