Prepare the smelling clues.
This activity can be done with one other person, or with a group. Either way, you'll want to prepare the clues in advance.
To prepare the clues, you need to gather fun facts about mammals. You can make as many clues as you want per animal, depending on how many people will participate in the activity.
Write the clues on cards, such as recipe cards or scraps of cardboard. Punch two holes in the corner of the card and thread in the holes a twist tie.
Next take cotton swabs and dab them in a scent. We found that lemon and peppermint worked well. Vanilla discolored the swab, thus giving a visual hint (which you don't want to do). Other scents you could use might be orange, chocolate or cinnamon.
