Paddy and Fluffy’s urns are almost identical. On impulse while at the pet shop the other day, I bought a little pet collar tag for each urn. We had one of these made for Mollie when she came to us, though she no longer wears a collar because she is not an outside cat anymore.
The machine does it immediately and you have a choice of tag, font, and text. I am really happy with how these turned out.
