Whether they know it or not, pets are a big part of Halloween, too. As long as their costumes are comfortable and non-intrusive there's no reason that a family pet can't be a part of the festivities. But just like their human counterparts, pet costumes can range from bland and uninspired to inventive and creative. As inspiration for your own pet's attire, here are some of our favorite animal costumes. Vote for your favorite, and if you've got a costumed critter, submit a photo below!
