You need to take photos of the damage and upload them into your PetCloud inbox to the Owner.  


If the damage is extensive, then you need to get a couple of quotes from a handyman as to how much it will roughly cost to fix the damage.
Try contacting one of these handyman sites and asking for a quote and photograph the quote and send it to the Owner through your PetCloud inbox.

If the damage is small, and want to fix it yourself go to your local hardware store or a Bunnings and tally up the cost of the sample pot of paint and spackfill and brush needed to fix the damage. Take a photo of the invoice and upload it into your PetCloud inbox and send it to the Owner.
