Idea Exchange: A simple way to keep a surgical site hair-free

To keep the surgical area free of hair when castrating cats, I cut a small diamond-shaped hole in the middle of a green rubber dental dam and place the dam over the surgically prepared testicles. I'm careful not to cut the hole too big or the testicles won't stay covered, and I soak the dam in cold sterile solution before using it.
