Actually, when they took away the petting animals from FW, they brought them to AK - so you'll see the same animals. And, don't worry about touching them. Just teach your kids to not touch them on their faces, so they don't risk getting bit. They can touch their backs, etc. (I'm thinking of the goats). It's a nice learning opportunity, and the kids love it!
There are hand-washing stations to use when they're done too!
