Sonvujunk Expandable Cat Backpack Carrier, up to 12 kg

Sonvujunk’s expandable cat backpack carrier is listed for pets up to 12 kg, with mesh ventilation and a fold-flat design. Its stated dimensions and load limit make pet fit the key consideration, while the airline-approved claim should be checked against your airline’s current carrier rules.
