Bests & Worsts Reviews from Amazon

These are not the same size as the regular sparkle balls that are sold at pet stores. These balls are much smaller and could easily be a choking hazard, especially for a full grown cat. The ball can fit inside an adult cat's mouth and while a mouthful can be swallowed without difficulty, These balls measure approximately 1" (25mm) when measuring the dense interior, not the sparkle filaments. The regular size sparkle balls sold in pet stores are approximately 2" with the jumbo size sparkle balls being more than double that size. Please see the attached photograph for a comparison of the sparkle balls. I honestly hope this helps someone make an educated decision. I will continue buying the much more expensive, larger sparkle balls from pet stores until I can find one that is comparable size. Saving a few bucks is not worth the potential risk to our kitties.
