I went in my studio last night to finish up a project and check on Cane and Reed, who were in there visiting Trish and TJ. The kittens were gone. Nowhere to be found. After searching and calling, I assumed they were napping in a pile of bags of batting scraps. I had made a very large sewing machine cover to keep cats out of thread, pins, and anything else I didn't want them to get into along with my machine when I'm not using it. I was proud that I could do something to keep one step ahead of the cats. When I tried to take the cover off my machine, it wouldn't budge. This was very strange. Upon investigation, I found the culprits.
It's hard to be smarter than a cat - or sometimes, even a kitten.
