Taco also does that
That's why I said he likes both
Typical Taco behavior: Sitting up there on the highest board of this climbing wall, looking out of the windows for hours, a clear view over the ocean and parts of the city (fisherboats going by, there is a bike lane, there are shore birds, there is a street and now also a construction site, and there are container ships on anchor and then suddenly moving into the port) and the balcony (there are many succulents, occasionally hummingbirds, and when I'm at home I often sit there; yesterday he watched me all the time while I did some woodwork on the balcony, 4 hours) - and then I hear a *scratch-scratch-bump!* and he has jumped down, gets in one of his caves, usually squeezing in tightly, and stays there for maybe half an hour and comes out again, maybe for hours until it's time to sleep.
Sometimes he stays a complete day in a cave, next day again up on the windows for hours.
In his caves, he likes to put his head on a stone, and dig deeper with the bag legs. Always head higher than the rest of his body.
If for any reason he can't look out of the window (there are curtains we close at night as the lights from the harbor and a parking lot are very bright, and when I get up and that's very early I open them, but when I'm not at home that's my husband's task and he often sleeps in as he works different hours and just isn't a morning person), Taco gets grumpy. He wants to know what's going on outside.
