My beloved cat has passed away, so I'm offering these items to someone who needs them. These items are new and unopened. I purchased them online for ¥1530 per bag. If you'd like, I can also include the therapeutic food in the can (just purchased from the vet) or some cat food packets, as shown in the pictures. The diapers were used for my cat, but they can also be used for dogs. My originally large cat, who weighed about 4kg, was able to wear these even after he became thin, and they fit perfectly without any leaks. There were few instances of the diapers coming off overnight or during the day when no one was watching. Please note that the flap for the tail is a little stiff (which helps with the fit), so cats with sensitive tails might not like it. Please understand that these items have been stored at home before purchasing.
