I'm pretty sure that it's a diffraction effect. Take a look at a DVD or a CD. That's caused by a diffraction grating, i.e. the grooves are lined up next to each and evenly spaced. The reflected light is split up into its component parts, a rainbow effect. My guess is that the hairs on the T's foot pads are very thin and evenly spaced to allow adhesion to slippery surfaces. The hairs reflect some light and the result is a very pretty iridescence. I doubt that it's much of a threat display, just a coincidence related to their ability to climb smooth surfaces.
