Not that this is a surprise...
Snip...
Veterinary clinics across the country that accepted offers of free “starter kits” of Hill’s Pet Nutrition’s new y/d diet for cats with thyroid conditions discovered afterward with dismay that accepting the samples meant they would receive shipments and bills for more food.
Practitioners from Florida to Washington reported on a message board of the Veterinary Information Network (VIN), an online community for the profession, that taking the samples apparently automatically signed them up for paid orders.
I would think Vets would be the LAST people they would want to pizz off.
