Product review (5 stars): Friskies Tender Hairball Control snacks
Both of our cats love these soft treats--and ONLY these treats! We give them these in addition to their indoor cat food to help keep down the hairballs.  A great thing since one is a long-haired Main Coon and the other is a meuium-hair Pastel Calico.  Getting them in bulk from Amazon is a HUGE money saver and convenient since these treats have become expensive and difficult to find in our area.  I recommend the treats AND the auto-ship option from Amazon!
