Most pet owners know to keep their animals shut in a quiet room during trick-or-treat night so they don’t dart outside or cause a problem. Tom Colvin, director of the Animal Rescue League of Iowa, says other Halloween concerns include not feeding pets chocolate, as it can poison them. Colvin says don’t leave treat bags where the pets can get into them. He says tinfoil and cellophane wrappers can be a problem.Colvin says the old adage about “curiosity killed the cat” can be especially true during this season of jack-o-lanterns. He says special care must be taken with felines and open flames. Cats can easily be set on fire via glowing pumpkins.While some people may think it’s cute to dress their dogs up as devils or Uncle Sam to accompany them for trick-or-treating, Colvin says that’s a big no-no. He says it’s just too stressful for animals.He also suggests making sure your pet is wearing the proper I-D tags in case it does slip out a door when the goblins come a’knocking.
