We've had strays brought to the store hoping we'd recognize them.
Collar is one, but no identification.
Where cats and dogs can't - or won't - carry wallets, we do offer a simple solution.
We have pet ID tags made right at Animal Essentials in a variety of colours and sizes. Usually folks get the pet's name on one side and address or phone number on the flip side. Some even toss an email address as extra insurance. Whatever you inscribe, it may come in handy if your pet somehow gets away.
