Don't forget to thank your vet too! And don't forget that for Musica to hit the 24-year mark, you had to have taken pretty good care of her as well! Still, that's great news, and it gives me hope that my brood will live nearly as long.
The vet is great -- he makes it a point to see her personally and calls her his "miracle kitty." He is sure Musica is his oldest client of any type of animal (I assume he doesn't have sea turtles on his clientele list).
FWIIW, Musica has alwas been 100% indoors -- I think that makes a big difference. Of course, she has always been ornrey and egocentric. I think giving in and letting the cat knows she IS the center of the universe helps a lot, too ;)
