As I type, Cali is having her morning nap in one of the two carriers. Each has a very soft fleece blanket, recently laundered with tide with Downey. My kitties love to sleep in them. In fact Diego was napping in his before I closed the door for our vet appointment on Thursday. I have the carriers out all the time, they're never put away so they're no threat. The blankets smell like my clothes so I think that helps too. I wish you all the best.
