My first two chinchillas were pet store chins ... before I knew better.
In some pictures it looks like a long thin nose ... BUT ... in one of the pictures that is almost a profile, he looks to have a fairly blunt nose, which would be good.
His fur is nice, his ears are placed well and his eyes look bright and clear.
He appears to have a pretty white belly ... I'd love to see a picture of him from the side ... in one picture it looks like the gray/white line on the side of his belly is nice and straight, but in another picture you can't see the white from the side at all.
Do you have any idea of his weight?
Compaired to most normal "pet store chins", he looks very nice.
I've seen some that are beautiful, BUT ... things like malocclusion, seizures and heart murmurs may not show up in a chin until it is 3 to 5 years old or older. Like Jamie said ... he could father many kits and pass that on before you found that there was a problem. Just think of all the chins that would also suffer his same fate.
Knowing what I do now, I would never breed a pet store chin, even if he/she did do good in a show. Abby, unless you get the pedigree for them, find and talk to the breeder, and get some back ground information on them, you would only be asking for trouble to breed a chinchilla that is "unknown". You never know what might be 'lurching' around in their past ... with the big beautiful cage you were given with them and the exercise wheel, I would just enjoy them or find them a good home. Them and their cage, wheel and all cost you nothing ... it's not that much to feed two more little mouths. Just love them or give them to someone that has the time for them.
That's what I would do/tried to do.
