Unfortunately, I had to put Buster to sleep today. He was diagnosed with transitional cell carcinoma of the bladder and lost the battle. He was an amazing cat and the best friend I ever had. He was my first pet and such an important part of my life. I found him on the streets in 2000 and he was with me throughout graduate school. I was hoping he would make it to see me graduate in June but he couldn't. I am so heartbroken right now. I can't stop crying. I love him so much.
