Very sorry to hear about your loss Myke. I had to put my cat Calvin down a few months ago and it was very hard to do (I still miss him a lot). I raised him from a 6 week old kitten and had to put him down at 15 years old. That's a long time to spend with a pet and I truly miss him. I'm sure it was tough for you and Cristine but you will always have the great memories of Roddy and that makes it all worthwhile.
Nice to see you adopted more cats...I made a promise to Calvin before I had to put him down that I would adopt/rescue another cat in his name (I adopted Calvin from a pet shelter when he was 6 wks old) and I plan to make good on that promise in early 2011.
Even though your new cats can never replace your loss, I wish you and them great times and great memories.
RIP Roddy & Calvin
