Most house sitting jobs require you to stay over night so that you are there for morning and evening feeds and to give the kitty more company in general. This is usually for a 12hr period from 7pm - 7am each day (as most will need to go to their day jobs during the day)
As a house sitter you will never be expected to stay in the house 24/7 but as with every booking each owner and cats requirements are different, some may be really old or really young and require extra attention, some may just enjoy greeting you when you come home from spending the day at work.
Always make sure expectations are very clear when confirming the booking with the owner.
