Release of "Expandable Backpack," a Carry Bag That Can Be Expanded While Keeping Your Pet Inside

Our expandable pet backpack, compact when on the move and expandable into a comfortable space when needed, will go on sale from early March at the PETs ADVANCE official online store. It will also gradually go on sale at pet supply stores nationwide.

This pet backpack is designed with the assumption of use for everyday outings, hospital visits, and travel. Building on that, we emphasized that "the exact same item can be used as-is" during disasters and evacuation destinations.

It is designed so you can continue using it according to the situation without needing to switch between a carry bag for travel and a cage for staying. Because you can expand the space with your pet still inside, there is no need to take them in and out when expanding, reducing the risk of sudden jumps or escapes so owners can use it with peace of mind.
