Used daily from purchase in 2023 until October 2025 (current). Operation confirmed. I think it's generally clean, but there is some wear and tear. Please check the images. One of the rods that holds the cord on the back is broken and missing. It's shown in the last image. Disinfected with Dover Alcohol after cleaning. Box included, no instruction manual, no filter. You can find the instruction manual as a PDF by searching online. You can use it immediately if you prepare a filter. Everything except the filter is included. There is styrofoam in the box. The box will be wrapped in a plastic bag for shipping. The cat receives a three-way vaccine every year and has no medical history. I observed it for a month, but it's no longer in use, so I'm offering it for sale. If you have any concerns, I will upload images. Please contact me.
