Chinchillas are often sick much longer than we know ... by the time you know one is sick, it may be to late.
I would definitely get her to a knowledgeable vet a.s.a.p. With a sick chinchilla, time is your enemy.
Blood is not good to see with any chinchilla. The fact that it is showing up in the urine or bowls, is even worse.
Dirrhea in a chinchilla should not be allowed to last over 24 to 48 hours, they can quickly become dehydrated.
Is this the same chin I suggested putting the white paper under on another post?
Please keep us posted on her condition and what the vet says.
