This collar is very flimsy. My cat's nails shredded the collar very easily when he scratched around his neck. As a result, one of the shredded fibers somehow wrapped around his bottom tooth while cleaning himself. He began making all kinds of choking noises and could not breathe due to the way he had to hold his neck with the collar around his tooth. I have been keeping a collar on him for 8 years, and I have never seen a collar fall apart the way this one did. I never would have imagined something like this could happen with a properly fitted collar. Other collars are much more money, but it's worth spending the money to keep your pet safe. It's an understatement to say I'm disappointed in this product.
