We have house sat for the owner twice now and have to say this has been one of our more unusual sits. Zeus was present each sit but the two cats were just a flash in the distance!  They are also very timid with the owner and we were warned about this. We fed Zeus each night and put food down near the pool for the cats. We were then able to observe them coming out from the bushes, eat and retreat!  Was never quick enough to get a photo of the two!
Both sits were weekend stays. This home is not far from our own and we were living in our house at the time and did the weekend stays in order to help the owner out as she was having trouble finding anyone just for the weekends. Walking Zeus was not an option also as he makes it to the fence boundary then refuses to walk any further. We were also advised by the owner that this would happen. 

Responsibilities included:

Security of the home
Feeding nightly both Zeus and the cats
