Paw was going to build us a new one, but since he works 6 days a week and never has anytime for anything else, Bow took matters into his own paws and ordered a huge cat enclosure from C & D Pet Products. It is preassembled before it is shipped, with all screw holes pre-drilled and the screws in place ready to be screwed tight. It went together beautifully. All the pieces are labeled so that you can tell what attaches to what.
With this enclosure, we set it up off the ground by placing 2x4s under the bottom of the cage. So any rotting that occurs will mostly affect the 2x4s. Plus, I can trim easily along the 2x4s with the weed eater and not worry about my string getting caught up in the wire.
We also ordered this one in a 7 foot tall version instead of 6 foot so that the top is now above the top of the windows.
You can also see the magical instant grass that I put down in October to replace the dying Asian Jasmine and to get rid of all the weeds. I don't know how well St. Augustine will hold up to the thundering herd of elephants of 40 paws, but here's hoping.
