I know I'm hardly ever on the cat side of PT, but I still have my 2 cats of course! My cats love going outside (I am outside supervising them of course), but the problem is with our new house they are able to climb the fence when my back is turned. I really want to make a safe enclosure for them so they can be outside and not get into trouble!

Has anyone made a fully enclosed (on all 4 sides) cat enclosure? If so, how much did it cost and how long did it take to build?

Thank you so much, any information would be appreciated!
