Yes. My cat C.C. She has a preference for eating soft fuzzy things. She has eaten the fringe off of blankets and scarves, cotton balls out of the garbage can, and is currently trying to consume the wall-to-wall carpet in my (rented) duplex. Sometimes, when I hold her, she tries to eat my hair. For the most part, I can keep these items away from her (except the carpet).
Her behavior toward these items can be quite creepy. Recently, I was sitting on the floor with her, removing the dead hair that gets trapped under her top fur. I was creating quite a pile of hair on the rug. Periodically, C.C. would get a voracious gleam in her eye and snap at the pile of fur. I moved it away. She still lunged for it. I noticed a small nail on the floor and (stupidly) added it to the pile, destined for the garbage can. Unfortunately, C.C. thought it was destined for her stomach. She lunged at the massive mound of dead fur, and I didn’t catch her. She snapped most of it up in one bite. I had to hold her down and fish the nail out of her mouth. She didn’t care. She was happy.
She knows the location of every cotton ball in the house. When we first moved in here, I left the box with the bathroom stuff (including cotton balls) stacked on the floor, with a lid but not taped, and another box on top of it. C.C. knew the cotton balls were in that box. When I went out for dinner, she shoved the other box off the top of the stack, opened the box with the cotton balls, and proceeded to chow down.
Fortunately, she has never given herself an intestinal blockage. But, when that day comes, I have determined that I will not pay for expensive surgeries to save her. I love her, but I can’t justify that kind of spending on a cat that will do the same thing again, and again, and again, given the chance. And, as you see, she makes her own chances.
When I investigated this behavior, I learned it is common in cats that are removed from their mothers too early. This was definitely true of C.C. She was living at a shelter without her mother by the time she was 5 weeks old. She is definitely neurotic. Sweet as can be (to me, anyway), but neurotic as hell.
