One of my cats (3 y.o. female Bengal, spayed) absolutely loooves the taste of the sticky side of tape - especially packing tape (or at least, that's what's usually available) but I've also caught her licking the double sided tape I put around electrical cords to deter her and her brother from chewing on them. She has no interest in the non-sticky side, and she usually doesn't chew on it that much as far as I've seen. I'm not bothered by this behavior - licking is at least a nondestructive alternative to chewing on the cords - unless it's bad for her or a sign of poor health.
Any idea about what's causing this strange behavior? It's been going on for months if not years, and she's got a clean bill of health from her last vet visit. She and her brother get the same food, although she is way more motivated by dry food than he is and preferentially consumes it during the rare times it's an option for her. But that doesn't seem enough for her to be experiencing some form of malnutrition, is it?
If this is a problem, is it something I can train her not to do? Or should I just keep her away from exposed tape from now on?
