I am building a concrete slab with radiant heat(pipes that run through the slab with hot water). I wanting to make a cement pond 7ftW x 10ftL x 3ftD for a caiman. Is there anything that I can put on the cement to protect the caiman's feet from rubbing raw? What kind of spray or rubber paint for example, can I use that would be non-toxic?
The caiman is about 4 ft. long and growing.
Any suggestions would be appreciated.
