I'm 22. I purchased Jasper(and Digit--RIP buddy!) July 29th, 2001. So I've had chins for 9 years this past july. Which means I purchased my first chinchilla at 13. Jasper is still with me, and lives in a pet cage with a rescue I took in, adopted out, he came back to me, I adopted him out again and he was returned yet again. So he and Jasper share a pet cage together.
I started breeding roughly 3 years later, and today I have a herd that consistently stays between 65-80 animals at any given time including babies.
