3. Chews on Weird Things
Okay, if you have a cat that likes to chew on odd non-food related items then there could actually be a problem that you need to be aware of. Cats that regularly chew hats, slippers, blankets, cables, etc. may have developed a condition called pica. This condition can be caused by a gastrointestinal issue or by anxiety. Much the same as humans chew on pens or fingernails when they are stressed and anxious, your precious cat may be worked up a little.
Either way, it may be a good idea to bring your favourite pet to the veterinarian if they exhibit this odd chewing behaviour.
