My cat buster was put down yesterday after a 2 month long battle with cancer. He was the best cat in the world and I've had him since I was 5. I knew it was inevitable, but I had high hopes I would see him again, but he passed without me around. My other cat, Sunny is very stressed and confused, because she grew with buster for 15 years and now hes gone, i think thats the worst part of this whole thing.
