What is the upkeep cost of a mount, animal companion, or familiar?


The section on animals in the Equipment chapter (Core 294) gives prices for renting or purchasing an animal. However, we haven’t been able to find any rules for cost of animal feed or other upkeep.

How much should I charge my players for the upkeep of a mount, animal companion, or familiar? I could understand that a familiar wouldn’t have an upkeep cost since it’s magical, but it seems to me that there would be expenses for mounts and animal companions.
