L.S.
This may not work at all, but I plan activities for a local mom's club, and we got o Pet Co! The have awesome field trip/tours and let the kids play/pet with the lizards, snakes, frogs, you name it. My son eats it up! I went on fieldtripfactory.com to register, and they were fantastic. I went to the one in NW Houston on FM1960 near Eldgridge, but I am sure all are great..and they do it for FREE! Might be fun to do then go to a place to eat cake etc.. just an idea..
