Looks like kitty was taking a nap in that T-shirt.
Just a thought but these pics have me thinking that for cats that need a burrito wrap (I've done that many times), it would be easier to slip a turtleneck sweater over kitty's head.
That way the feet are already gathered (would still need folding at the bottom) and the bunchy neck could be pulled up as far over face as needed. I'm sitting here wondering how that would work with clipping my Calico's claws. She doesn't bite or scratch but turns into a twisty worm when I try to clip so have been taking her to the clinic for that instead of wrapping her. Would need a kid size and she's smaller than average (7lbs). The sleeves could be cut as short as needed and might be easier to get the front legs out and back in that it is with the wrap fold. Now I'll be looking for an itty bitty turtleneck sweater or even a mock neck for this little girl.
Thanks for the idea, Orion2!
