Product review (5 stars): Great product - why are stores not selling it anymore?
It seems that Petsmart and other pet supply stores have discontinued this product.  I have been buying it for my cat for about 15 years and she thinks it's a treat.  The main thing is, it works and she never has hairballs.  It's a great product.  I bought a box of 10 bags here because I don't want to run out.  They will last over a year for me as I only give her 3 a day.
