I've been in DC for the past days, and of course I had to go visit the small mammal house at the National Zoo. They have several habitats of rock cavies there, and they are so much like domestic guinea pigs! I watched one cavy barber another, and then poke and bite the others rear. The victim scurried away annoyed, and the first one was so delighted it started popcorning!
And here's the only decent picture I could get of a rock cavy...it's hard to take pictures of moving animals!
