CattyMan Pet Play House Connect Tunnel The connector part has been chewed by the dog, and there are cracks in the plastic parts. Therefore, the overall condition of the product is considered poor. You can also combine it with a straight tunnel type (three-connected), but because the connector part is cracked as shown in the photo, it will likely break further with repeated connections, eventually making it impossible to connect. As shown in the first photo, if you combine it with a three-way tunnel type, there is less damage to the connector part, so it's currently okay. The product itself is relatively clean because it has been used only a few times, but there is damage to the connecting parts, so please refrain from purchasing if you are concerned.
