Can I mix and match different collars and tags?

For a perfect fit, our cat tags are designed exclusively for our cat collars, and our dog tags are meant for dog collars only. They don’t interchange. Dog tags include a versatile hook that fits any collar up to 0.98 in (2.5cm) wide, and our airtag holder works wonderfully with both our cat and dog collars, as long as they are up to 0.98 in (2.5cm) wide.
