Basically, we prefer joyful common sense contact during the video call 
That usually saves everybody a lot of hassle afterwards.
We go the extra mile for the pets, communicate daily with photos and videos, and genuinely try to make the sit a relaxed and pleasant experience for everyone involved.
Most people honestly do not regularly check expiry dates in cupboards, and somewhere in the kitchen there is usually also a half bottle of wine quietly waiting for its next adventure 
We personally do not like wasting food, wine or perfectly usable products, so we often simply use them instead of throwing everything away. Apparently in modern times this can sometimes be seen as ‘risky behaviour’, but after more than 20 years of travelling, hiking and surviving questionable kitchens around the world, we are still very much alive 
And the same goes the other way around. We are also perfectly happy to leave behind opened expensive bottles of liquor, fine pasta, chocolates or other good things for the next people. Life is too short for panic over an already opened package of pasta.
Until now we have never had complaints about that approach.
Our last sit was another really lovely one. One of the cats needed medication and extra care. We tried to make that as comfortable and stress free as possible, although for the cat it unfortunately remained a bit of an unpleasant experience anyway.
The HO invited us for dinner exactly during the time we would normally have been cleaning the house before departure. Honestly, it was not necessary at all because they already had a cleaning person arranged for that.
For us that is the ideal outcome: a win-win situation, good communication, happy pets, relaxed humans, and sometimes even new friendships on this tiny big planet
