So, my cat, Luna loves to chew on tape (like packing tape on boxes, rolls of tape, or things that crackle like tape.) I'm wondering if this is a problem. Whenever I hear her doing it I take it away from her and keep an eye on her to make sure she doesn't swallow any of it. Though i've seen her occasionally chew on the tape on a box for a second then leave and go away. She also likes to chew on pens and rubber/plastic things. I don't know how to keep her from doing it when I'm not around (when I'm around I just tell her "no" and she stops)
