I bought more food for the dogs. Will Rover reimburse me?

My client's business trip was extended from 1 week to 2 weeks unexpectedly and the dogs ran out of food. I offered to buy more food for the dogs, the owner approved and said that she would reimburse me. I sent her a photo of the receipt 2 days ago ($40 worth of food!) and haven't heard a thing from the owner. I assume they're busy with work and the stay doesn't end for a few more days, but it's a little weird. I'm not in a rush to be reimbursed, but I would expect it by the end of the stay at the latest. If they never reimburse me, is that something that Rover will cover? Thanks.
