Bests & Worsts Reviews from Amazon

These have been a staple for our cat's enjoyment since we got him three years ago. They're everywhere throughout our house. Guests have returned home only to find one in their suitcase. However, sometime back our cat had a sore in the corner of his mouth and lower lip. The vet could not determine what it was and gave us a liquid medication to apply as needed. The condition would get better and then come back. These springs often get tangled in electrical cords or stuck under a piece of furniture, and the cat will pull at them and sometimes the end will snap back out of his mouth. That got me thinking that the relatively sharp ends might be grabbing at his lip when they snap. So I tried blunting the ends of every, single spring toy in the house by using needle nose pliers to bend back about 3/16" to1/4" of each end onto itself as shown in the photo. I've been doing this for about four months and there have been no issues with lip sores. Having to make this modification is the only thing keeping this from being a 5-star review and ending with the first paragraph. While it would increase the cost, it would be wonderful if the manufacturer would blunt the ends so this modification isn't necessary.
