A cat carrier is a portable container designed to safely transport cats. It typically features a sturdy structure, ventilation holes, and a secure door to keep the pet inside. Carriers come in various sizes and materials, including plastic and soft-sided options, making them suitable for different cat breeds and travel needs. Using a cat carrier is essential for trips to the veterinarian or during travel. It helps reduce stress for the cat by providing a familiar and secure space. Many carriers also have handles or straps for easy carrying, ensuring both the owner and the cat can travel comfortably.
