Put on your cloaks, scarves, and robes and dust off your wands, because the Harry Potter pet walk, costume contest and birthday party are all happening on July 29 in Fort Collins. Tarantallegra!

Saturday's festivities will kick off at 11 a.m. with the pet costume contest, but participants and their muggles are asked to meet beforehand at 10:30 a.m. outside the front doors of Old Town Library. The costume contest includes categories like “Cutest” and “Most Fantastical Creature.” The walk departs at 11:40 a.m., where all pets must be on a leash. After the walk, participants can reconvene at Library Park to make blankets for local animal shelters.

For more Harry Potter themed fun, head over to Old Firehouse Books in Old Town, where staff will be celebrating their favorite wizard's birthday from 6 p.m. to 8 p.m. Admission to the party is $5, and includes refreshments, cake, activities, and trivia. The birthday bash is intended for kids 5-years and older and costumes are encouraged.
