Plastic carry bag, suitable for air travel. - Model Name: AIR TRAVEL CARRY - Color: Brown - Material: Plastic - Type: Carry bag Thank you for looking. I used this 3 times for my kitten's regular check-ups. However, since my cat grew into a large breed, it seemed too small, so I purchased a different one and am now selling this. The condition is clean. There are no significant stains or signs of use. For a normal-sized cat, even an adult cat should have plenty of room. I recall purchasing it at a pet shop for around 7000 yen.
