Yes, ventilation is a key factor to consider when choosing a carrier for your cat. Adequate ventilation ensures that your cat receives enough air flow, which is essential for comfort and reducing stress during transport. Look for a carrier with multiple sides of ventilation, allowing for ample air circulation. This is especially important in preventing overheating and ensuring your cat can breathe easily, making the journey more comfortable and safer for your feline friend. A well-ventilated carrier contributes to a more pleasant travel experience for both you and your cat.
