Animal Alert Cards are intended to signal care for your pet if you've become incapacitated. The care will indicate the pet's needs and temporary care instructions in your absence. The card is self-laminating to seal in written information and eliminate smudging. The cards are about the size of a credit card which make them suitable for purse or wallet. This refill pack comes with 100 cards and is perfect for veterinary practices and related animal handling services/businesses.
