Before the trick-or-treating begins, put your guinea pigs in a safe, quiet room away from all the festivities. If you would like to dress up your guinea pig in a costume for a photo opportunity, make sure they only wear it for a couple of minutes and you supervise them at all times. Don’t use costumes that restrict breathing and visibility. Make sure that the costumes components cannot be ingested. Creating photoshopped costumes is the safest method!
