Over my lifetime, I've always had a multi-cat household and am use to all types of personalities and natures of my fur kids. A good share of which have been "chewers" who love to chew on a variety of things. One especially loved plastic, foil, and string... and would eat it if allowed to! This is why I don't recommend this toy. I'm very particular about my selection of cat toys and check them over for anything that could be a swallowing hazard (small plastic eyes/noses on mice, very small metal jingle bell type balls, etc.) I want to be sure if my cats play with them that they will be safe, supervised or not.
I've checked out this particular style Crinckle ball toy and no where does it say "not suited for chewers" which I think they should have on toys of this type that pieces can be very easily chewed off and swallowed. There are few toys out there that are designed for specifically for chewers at pet stores, so if you have one or more of these fur kids, I recommend you buy those toys over ones like the Crinkle ball. There are some "Chewer" toys sold out there also that support pet charities as well!
So ultimately it comes down to this, know your fur child and buy with safety in mind!
