Build: a Cat-proofing enclosure?

Chicken pregnant, you should keep in mind: Question Snake Keeper Mad : Cat-proofing an outdoor enclosure I have a forum of about 5x3 exterior made from wire and metal studs for my bearded dragon. He spent a few hours on the road every afternoon, under strict supervision. We have four cats in the neighborhood, all very sweet, but very curious. How can I get a cover on top to keep the kittens I'm sorry, maybe I did not make significantly (more mesh screen must allow sunlight through it?):
