As temperatures drop, mouse friends make a run for shelter. Children will learn how field mice keep warm in cold weather, make mouse masks, and look for mouse hideaways on a nature walk. After the walk, they’ll read animal stories and warm up with hot chocolate.

Classes are open to children ages 3 to 5. Pre-registration is required. Enrollment is limited to 15 children, so early registration is recommended. Sessions include eight classes; all classes begin promptly at 10 a.m. The fee for a session (eight classes) is $55 for members and $65 for the general public. Each class includes a snack and a craft. Programs are led by popular children's teacher Jenny Houghton.
