Self-cleaning cat toilet with a spherical design. - Design: Spherical cat toilet - Brand: CIRCLE - Function: With automatic cleaning function - Internal structure: Disassemble-able internal structure - Color: White I am the second owner. My beloved cat grew faster than expected, and after six months, it was no longer able to use it inside. I spent a considerable amount of time cleaning it, but I couldn't remove the remaining powdered cat litter. The tape inside was likely applied by the previous owner to prevent sand from getting in. It did not interfere with the operation. This is a used item. I can explain how to disassemble it, but I cannot accept claims for issues such as it not working. By the way, I just turned it on, and it worked normally.
