I am so sorry for your loss. Cancer took my Sissy kitty last July - but we only had 6 weeks with her after the diagnosis. Be ever so thankful you got that whole year to say goodbye. Run free little eightball!
Sorry for the loss of your dear, funny kitty. You saved him from the rafters (and his hoodlum mother), and he gave you lots of giggles for the next 13 years.
