Tre was at least 15, and possibly more when he died last month.
Tiny is my oldest now, and she just turned 12 last month. Thufir is about a year behind - I gave him the same birthday as her since I don't know what it is, so he's 11 now. My 'baby,' Promise, will be turning 7 in May. I can't believe that the little bitty kitten I found out in the alley will be old enough to be considered a 'senior' cat.
