Setup

Gather only common or recycled items needed to build a carrier from a small box, cutting a door with adult help and adding a soft fabric lining. Place the materials beside a simple recording sheet or blank paper, and prepare the Pet Carrier Test Center challenge in one working area; no digital device is needed.

Activity

  1. Measure a few stuffed animals and predict what size box and opening each one will need to fit comfortably.
  2. Build a carrier from a small box, cutting a door with adult help and adding a soft fabric lining.
  3. Test-fit each stuffed animal, discovering the biggest one doesn't fit through the door, then widen the opening and retest.
  4. Deliver every stuffed animal safely to the vet in its properly sized carrier and explain the measurements used.
