The time has come for people to don masks of heroes and villains, historical figures and figments of fantasy.
But how many pets will join that mix this Halloween?
The Gazette asked its readers to share their favorite photos of their pets in costumes ahead of the holiday. Outfits ranged from punny — a "rufferee" — to dignified — a gentleman, complete with a top hat.
Dogs dressed as humans (a cheerleader and a pirate), guinea pigs sported honey bee and spider suits, and one dog even went as something tasty — a hot dog.
