@iamplankton We are Hos and sitters. In our experience, no, toiletries are not left by us or for us. This is house-pet sitting in exchange for free lodging.
As HOs, we do leave enough paper products for the sitter’s stay. And enough pet food and supplies for their stay (and then some!).
In the kitchen, they are free to use all the spices, herbs, sugar, oils and vinegars as they wish. Condiments left in the fridge are theirs to use freely, as well. And we do leave basic food for their first morning: coffee, milk, bread, fruit, cereal, eggs, milk, and basic aromatics (onions, garlic).
