"You definetly want to think about age of the animal. Are you in the position to adopt a puppy or a kitten? Do you have a lot of free time? Do you have flexibility in your schedule? Maybe you are looking for an adult cat or an adult dog. I think age of animal, size of the animal, species, breed, those are all really important factors to take into consideration any day of the year, not just Christmas," said Jeana Roth from the Animal Refuge League of Greater Portland.
