In a fit of persistence or insanity, the cats and I are spending the night in the camper again. I have rum. It may be necessary.
I have not only rum, by the way. After Darcy’s failure to appreciate the joys of camping the other night, I have two weapons. I have the kitty tent, given to me by a friend, and I brought the cat carrier. Both are quite friendly, safe places the cats enjoy.
Oh, I forgot. I have something else. I have catnip, and now, so do the carrier and the tent. This may work…

Good luck!
It seemed to have worked. They were a lot easier with the camper last night, and both slept until their usual 4:30. After the half hour they normally spend terrorizing at that point, they both went back to sleep.
