I purchased this last year but ended up not using it, so I'm putting it up for sale. This carrier can be used for both dogs and cats. It's a backpack type, making it easy to move around. It has viewing windows on the top and sides so you can check on your pet from time to time. Please refrain from price negotiations. Please cooperate with simple packaging. ※No claims, no returns. ※Returns and cancellations are not accepted to prevent product substitution.
