The Crenailro outdoor cat enclosure uses a lightweight mesh exterior that lets in plenty of sunshine and breeze while allowing your cat or other pets to see everything around them.You can set it up indoors or outdoors for a super-versatile and super-fun play space. Because cats love being outside! Even lifelong house cats can't help but be curious about what's outside the front door. A safe, portable outdoor cat tent is a great way for brave cats to get a feel for the great outdoors without any danger. Notice?? Our large cat tent and cube include a waterproof and dustproof mat. The product comes with 12 ground nails to fix tents and tunnels. Can be used alone because both sides of the tent are zipper sealed. Each tunnel has an airtight zipper for secure closure.
