the Snow Tigers are very beautiful, and I like the regular tigers as well
The Free ones are my favorites.
Elephants are exquisite creatures...their ability to bond /mourn/ care for others is amazing to me. Not too mention their size and abilities.
Unicorns, but have you noticed, they're fewer and fewer? The late great Ken Allen at the San Diego Zoo. He was an orangatun and always got out. When I bought my best friend to see them they just stared at each other--I think they may have been having a mental bonding going on.
The wild guinea pig enclosure -- I just love it when they stampede
The BIG CATS!
All the animals out the Zoo are my favorite.
