Can't sit still?

A neighbouring family has gone to Europe for a month and they let us know in advance that a professional house-sitter would be caring for their place. Curiously, the person doesn't appear to be staying in the house, instead swinging by throughout the day to feed and play with the dog, take in the mail, put out the bins, etc. Could they be looking after more than one property at the same time? Personally, I don't class that as "sitting". I did a bit of home-minding in my younger years - several weeks' worth, in fact - and for me, it was all about fully immersing yourself in that suburb.

Recommendations: strong sequel "Squid Game 2" plus "Rugged Rugby" [both Netflix], adult cartoon "Creature Commandos" [Foxtel], the hugely entertaining "Roundup" cops-versus-gangsters fillum series [Kanopy (fourth instalment not out here yet)], the "History Extra" Podcast's five-parter on Tudor England, anime "Solo Leveling" [Crunchyroll]. While I've given up trying to record all of the media I consume, I'll keep noting the best stuff like this.
