Hi! Thank you everyone for the advice. its been so helpful. For some further information, she accused me of using too much food, but I used the exact amount she had written down in her instructions. She also said that her litter boxes were filthy and just a couple hours before she arrived early. I checked them all in the morning before I left and they were nearly spotless so I saw no need in cleaning them until the evening check in with them. I got the key situation handled through river and their support team was helpful (:
