A while ago, we took in a chinchilla who had excessively chewed his fur. When he came to us, in fact, he had chewed off every bit of fur that he could reach-- in some places, down to his very skin. We constantly commented on how he looked-- like half a chin, like a kangaroo, and so on. We dubbed him Buffalo Bill.
Now, three months later to the day, Buffalo Bill is beginning to show his improvement. He enjoys hanging out near the boy chin in the next cage over. He has stopped chewing his fur and you can see it's growing back in tufts. This pattern of fur growth is completely normal. In just a few more months, he will look like a regular, fluffy chinchilla again. Check out how he's coming along!
