Using this pet backpack is easy. Just open the zipper, place your pet inside gently, and adjust the shoulder straps for a comfortable carry. When choosing a backpack, consider the size of your pet to ensure a proper fit. For cleaning, you can wipe the fabric part with a damp cloth and use a mild cleaner for the ABS+PC parts. Store it in a dry place when not in use to keep it in good condition. Always check the zippers and straps before each use to ensure safety. Also, don't keep your pet in the backpack for an extended period without breaks.
