Hi Sarah,
This is a fantastic question and a common problem. I have personally seen cats that have ingested multiple foreign bodies needing surgery because of this issue. There are many reasons why a cat may ingest items that are not food or are dangerous. Certainly, as you alluded to, it is important that you ensure your cat does not have any underlying health problems. I know that there have been reports of pica disorder in cats (behavior of eating non-food items) being related to diseases such as inflammatory bowel disease, allergies, and also stress or anxiety problems in cats. You may want to have your veterinarian do some diagnostics such as bloodwork to see if anything is amiss. Avoidance, as you have been doing, is likely the best thing you can do aside from working to identify a specific underlying cause. You may also want to discuss a diet change or supplements with your veterinarian as well. If you witness your cat eating something she shouldn’t, then definitely having her into the vet right away is the best idea. This will give us the best chance of preventing life-threatening complications.
I hope this helps.
