That could be my Charlie. When she was younger and sat in a cardboard box she'd chew on it sometimes.
Also the late Bandit. He did the same to plastic bags as well - and that ... might have had something to do with his cancer issue...
Need to get new account in some place I can dump photos so I can put kitty pictures here. Some time next week I will start introducing my kitties. Today played with each with the same toy back to back and scents didn't seem to bother them. Next will sneakily switch blankets and stuff. Wish me luck.
I use https://postimages.org/ most of the time. It's never been as troublesome as the "bigger" hosts. Also Tenor and Giphy for hosting my own animated gif's. There's also the TrekBBS Member option, where you can directly post images up to a certain size.
