Full description

A hard-shell capsule carrier that holds its shape in the car and on the move, with a metal grate door at the front and vents around the sides. The rigid shell protects a small pet from being squashed in a crowded back seat, and the smooth interior wipes out.

What you get

Hard shell with a moulded carry handle
Metal grate front door plus side ventilation
Three sizes: Small, Medium and Large
Wipe-clean interior

Before you travel

This is a rigid transport crate, not a soft backpack. Measure your pet standing up and check it can stand and turn inside - a capsule that is a centimetre too short means the head is against the roof for the whole journey, and the pet will spend it trying to back out.

In the car

Strap it down or wedge it behind a seat. A smooth hard shell on a smooth seat slides easily, which is the one real drawback of the design; a rubber mat underneath fixes it. The grate door gives airflow without letting a paw or a nose out into the gap between seats.
