A brief history.

I used to breed African Lovebirds and bought this small metal aviary to house my Black Masked Lovebirds due to a mouse problem at the time.

It was dug into the ground and surrounded by paving bricks 2 deep, on edge and with a walking path around the aviary of 3 wide. There is gaqlvanized tin 18" wide buried around the perimeter of the aviary.

I NEVER, EVER had a mouse problem in that aviary ! The big avairies, yes, but this one no.

A few years ago it was laying idle after I had sold all my birds to go work in the States and my son converted it into a frog habitat.

As he had tree frogs, to stop them escaping he covered the open, wired areas with shade cloth, sealing it with silicon to also stop the crickets we fed to the frogs escaping and creating a deafening noise in our yard at night.

Again never had a problem with mice, they love both frogs and crickets.

Son "finds othr interests" abandons "frogarium" and so dad converts it to a GH. I dug the floor out to 2 1/2 feet, put in 1 1/2 feety of paving sand, compacted it hard, laid pavers on the floor, and around the edge where I had dug out, laid pavers on edge and cemented them around the inside perimeter of the GH.

NO WAY can a mouse get in there unless they chew on the shade cloth, then there would be signs of "forced entry.

At present it is also sealed inside and out with bubble wrap as insulation against the cold. The only venting is high up near the roof and to the best of my knowledge I haven't heard of a mouse yet that can scale verticle tin walls 6 feet high !

So BILL, yes it is sealed and the dimensions are L 7 feet, W 5 '5", H 6' 7".

The short answer is if I build something, a lot of planning goes into it before the first nail is hit, measure twice, cut once. I have been a technician all my life and build things to the same phylosophy.
