Rowan and I were out in the yard after dark last night. I’d heard rustling in the field across the road and shined a spotlight over there. The cows were hanging out, chewing their cud, eyes shining. Good old tapetum lucidum. :) I thought it would be neat for Rowie to see the glowing eyes, so I got her shoes on, I grabbed a couple of glowsticks for her to play with, and we went outside.
