I never have collars or tags on any of our cats for fear of them getting caught up in something when I'm not home - they ARE bengals, after all, and trouble gets in their path when least expected. All of our cats are microchipped so that they can be identified if turned in to a vet clinic or rescue facility. In Uno's case, however, I have decided to go that extra step and purchase a reflective collar and I.D. tag in the event he slips past us, unnoticed.
Uno is such a smart boy, and he's enriching our lives in ways we never could have imagined. We are such a fortunate family to have him!
