RORAIMA outdoor use Instant Portable Cat Tent or Habitat with Rain Fly and Two Entrance for Indoor Cats, Air Ventilate Mesh Fabric Prevent Bugs, Size 75" L X 60" W X 36" This is a great #cattent for your little fur babies. It will satisfy their need for the outdoors while satisfying your need to ensure their safety. My Billy is a scardey cat but he also craves adventure. Every time I open the door I have to make sure he doesn't dart out. (even though when he does it's not even a few feet away from the door) This tunnel will help him get that itch scratched for outdoor life, with the breeze and all the scents available for him to fully experience. The mesh will keep him secure from large insects, but smaller ones like fleas and ants can still get through the holes of the mesh. It's big enough for more than one kitty (Sheba loves it too and she's quite the little adventurer) and it can work for more than one type of pet.
