I'd also ask if the fosters even have pets of their own. If not, so the questions would be very different to ask is how much are they aware of what is needed to foster. Do they, or can they get bowls, provide plenty of drinking water, provide a bed and so on?
First time fosters with no pets may need more information what is needed, if they qualify.
The organization I foster for provides the food, and medications if necessary (if the cat or dog needs it), as well as materials for kittens that may need be fed frequently.
The check list may be different for those who don't have pets of their own, or have small animal pets like guinea pigs in cages. Foster cats or dogs may be too interested in hunting smal animals, so that has to be kept separate.
Just pointing that out. Something to consider.
