I just found 1/2" hardware cloth on Amazon that's actually cheaper than the 1" I already got.... Where was I looking?!?

(the 1" came from Amazon as well, still cheaper than any store). Oh well. At least I only got a "test roll" of 25 feet, and not the entire amount I'd need. I'll use it on the vent openings way up there.
I still have those 2" welded iron panels I got for free from a neighbor though... I don't know what their gauge is, but they are like zoo cage serious - thick non-bendable iron mesh and an L beam frame around each panel, 3'x4'. She'd assembled them like tiles for the walls and roof of her run without a wooden frame, just the panels bolted together. I still want to use them... just worried that 2" may be too big... Maybe if I layer hardware cloth against them along the bottom 3 feet of the walls, and hope creatures get discouraged and think it's dense all the way up, and don't climb 3 feet up to check?
