About 1,500 of the 6,500 people expected to attend the convention dress up in full-body suits that make them appear to be animal characters.
These "fursuiters" will take part in the Fursuit Walk on Saturday at 2 p.m. It's a parade around the convention center. People are invited to watch along Tenth Street, next to the waterfall feature.
According to VisitPITTSBURGH, Anthrocon will contribute to $6.3 million in direct spending for our region.
"We are always pleased to host Anthrocon's annual convention," said Craig Davis, CEO of VisitPITTSBURGH.
Anthrocon has raised more than $240,000 for animal-related charities in Pennsylvania. This year it has selected the Pittsburgh Zoo & PPG Aquarium as the charity it will support.
The convention started in Albany, New York.
