I think he’s already taken it over. I have opened the front door a couple of times and he zipped out of it.
It might be why mine stay in when it’s cold. Ginger has a hidey-hole in the storage shed at the back of the yard that I’ve put a soft towel in for her, but Peaches just has me. sigh. LOL! Even before Ghost, he wouldn’t go in the carrier. I think he didn’t feel safe...felt trapped.
Aaaaaaaah, it’s his carrier already, is it? LOL! I didn’t think he’d be comfy in it - - that he’d feel about it the way Peaches does.
When our cats stayed out at night, they didn’t like being in enclosed places. I had boxes with blankets in different sheltered spots for them to curl up in and they used those.
Now they only go out during the day and if they get chilly, they come back inside.
