A cat carrier is a portable container designed to safely transport cats. It typically features a sturdy structure, a secure door, and ventilation holes to ensure comfort during travel. Carriers come in various sizes and materials, including plastic and soft-sided options, catering to different needs and preferences. Using a cat carrier is essential for trips to the veterinarian or during travel. It helps keep the cat secure and prevents escape, reducing stress for both the pet and the owner. Properly introducing a cat to the carrier can make it a familiar and safe space for the animal.
