Bests & Worsts Reviews from Amazon

I do not recommend these thin springs at all especially for kittens in particular. My 12 week old kitten started to lose weight and failing to thrive when he was always the largest and strongest of a litter I am fostering. A barium study revealed 5 broken pieces of these springs in his GI tract which will now have to be removed either endoscopically or by surgery if the pieces migrated to his intestines. This would have killed him and/or caused perforation if not caught in time. I can't tell you how much I regret buying these toys. These kittens were carefully supervised for a month during playing before the one kitten ingested them a few days ago. UPDATE: My kitten is doing great now and we were lucky the pieces did not move beyond his stomach. I wanted to clarify that my kitten swallowed pieces of the Ethical WIDE Colorful Springs Cat Toy and Ethical THIN Colorful Springs Cat Toy which were both plastic. The thin and narrow version is brittle and do not coil and spring back like the wide version. They also broke easily. Despite the breakage, I don't believe my older cats would have ingested the pieces like my kittens. However, I do not want to take a chance moving forward with the wide coils either and wanted other pet owners to be aware of the potential danger.
