Well, we have a kitty carrier on the front porch that is out of the elements, so if they are smart they could be in there. Or on a window sill or in our shed. You know...kittehs are very smart about staying dry! :)
If they’re anything like our cats, the carrier is the last place they’d go. Carrier = trip to the vet. LOL!
Probably in the shed. Doesn’t seem like a window sill would be much shelter.
