Heidi and Sean are doing well and are at least semi-legal. Their licensing fees are now on online billing, but now I need to provide microchip numbers, which were never asked for before when I had them memorized. As for the kitties themselves, they're enjoying their rebel status too much to cough the numbers up, but I have a secret weapon: PACA's microchip reader. Now I just need to get my hands on it.
Edit: Or just them sit still for long enough to read their additional collar tags. Sometimes they hate the fact that we're bigger than than they are. More so than others.
