Are these products goat proof? Not desired by other farm animals to eat? Hold up to sun, warping, curling, contracting in weather extremes?

Our Pre-Cut Regrind Rolls aren't goat proof but are typically not the first choice for an animal to eat. If these rubber rolls are not adhered down, there is potential for any animal to eat the rolls. These rolls are weather-resistant but would expand and contract in extreme weather. The rolls won't curl or warp but may buckle if there are many rolls installed next to each other. These rubber rolls are not UV stable, so they will fade over time in direct sunlight.
