What a bunderful question.
I'm usually up about 5:30am every day - the result of way too many years of wanting to be at work early (flexi time days) so when I come downstairs, Hillian are cosied up together in the kitchen/diner. Henry is usually on guard, Lillian sphynx like and half asleep. She expects breakfast nomms early so I have to top up the bowls with small handful of pellets and some freshly chopped and sliced greens, a smattering of parsley and every few days, a few slices of carrots. If it's nice in the morning, I'll let them out for a run - Lillian is usually pushing her nose at the back door wanting to go out. Henry usually retreats to the sanctuary of the box house in the kitchen and Lillian will have a short run outside. If it's not so nice, they come into the living room and Henry demands to be let into the hallway and kitchen and then he goes upstairs and sits on the landing outside our bedroom. Lillian just sits under the table.
I'm at work from just before 8am so they are back in and tucked up for the day with the radio on so (quiet) they feel not quite so alone.
I'm back at about 5:30 and they are let straight out and they stay there til about 7:30/8pm whilst I cook and keep an eye on them.
Once in, they sit in the living room under the table and chill.
At about 9:30pm, they both take themselves into the kitchen to bed. Henry usually goes into the box and Lillian sits in the open on the soft mat, eating more freshly chopped greens and parsley and perhaps the occasional redcurrant for taking themselves to bed.
Weekends they tend to go outside for longer and, on days like today when the O/H is off (halfterm), then they have the option to stay outside or come in.
I try as much as I am able to, to allow them to have their own choices and give them the freedom when they want it. But I also want them to feel as though this is their safe sanctuary and their default go to place if they feel they need it.
