Using Great Stuff, I filled the gaps between the styrofoam and wood framing. I also padded the corners

In a couple of days, I will trim and sand the great stuff to make smooth transitions from framing to styrofoam and also to round out the corners. I figured round corners will make for easier cleaning.
I also picked up a bag of Shur-Crete today from Sherwin Williams. Its a spray concrete/acrylic powder that we mix with water to texture swimming pool decks here in Florida. I figure the acrylic properties in it will allow for more flex than grout.
After the Great Stuff is set and cut, I will start to spray the texture. Tomorrow, however, I hope to set tile on the floors of each cage.
I also got the guy at Sherwins to give me a "sample" of tint they use to tint the paint to add to the shurcrete for built in color.
