A short while ago I attended day-long veterinary students’ “Behavior Club” meeting. It was truly something. What a line-up of speakers. As I milled around after the meeting, I struck up a conversation with one of our basic science researchers. A “mouse scientist”, so to speak, she began talking about her murine experiments. “I have just learned that mice can see ultraviolet light”, she said. Now all my experiments will be messed up because I did not allow for that.”
“What do they see in the UV range?” I asked.
“Oh, urine marks,” was the curt reply.
“What,” I exclaimed,” you mean mice see urine marks as well as smell them?”
“Yes, that seems to be the case,” she said dejectedly.
Then we got talking about dogs and cats. What if they could also see in the UV range? Then it struck me. I bet they can. I went digging around on the Internet for evidence to support this crazy notion.
