Kona turned two with the new year. We don't know his exact DOB, but given his age at adoption, it would have been late December or early January. For simplicity, we count his age from New Years Day. Coincidentally, our cat Moose was born around the same time of year and we've always counted his age from 1/1 as well. Moose turned 20 (!) yesterday. He's a bit thinner than he was, and sleeps a lot, but is otherwise a healthy feline. Mazeltov, boys!
