Make sure that you keep Frank real quite for a little bit following up the vet visit. Stress can really inhibit their immune sys. and recovery time, as I found this out the hard way. I took a male Jacksonii into my (newly acquired) vet to trouble shoot some symptoms, he drew blood from the tail...
What about fiberglass mesh? That is what I used, I framed the cage using screen window frame and used grey fiberglass screen for the top, bottom, and sides. Seems to be non-abrasive and looks nice..
