Yes, hard for me to believe she is 6 too. She was why I got on the internet, why I got my own computer. I actually didn't worry much about her at all. It was not a really invasive surgery and I had confidence (apparently well-placed) in the vet.
To be the most correct, I got her maybe 5 1/2 years ago around Christmas. She was an adult at that time, near her current weight but not completely grown up. I was told she was born that summer.
