- Type: Wire cage - Color: White - Size: Approximately 80cm x 30cm x 30cm - Material: Steel I made this to catch my cat, who had escaped. After about four tries, I finally managed to catch her. The mechanism is such that when the cat enters and bumps against the body, the hook comes off and the door closes. It's secured with zip ties, but please tighten them further if necessary. Removing the zip ties makes it quite compact, but I don't think it's necessary, so I'm offering it for sale in case anyone needs it. I made it myself because it costs around 10,000 yen on Amazon, etc. Thank you for looking.
