In this experiment it appears that Jenny might have some ability to discern motion. This came about this morning when i saw her focus in on Simon's tail which was barely twitching and she jumped on it. Now in the past we thought what appeared to be some sight (despite lack of response to the laser) was just reacting to air currents.
So in the Video i show her my hand, not moving and she walks right past it. But from several feet away i start wagging my fingers and (after a delay while she scratches herself) she homes in on it and pounces. I'm very dubious that these are air currents on her whiskers, but might that be possible? Will talk to her Vet today, Dr. Jenn. And yes, in case you forgot or didn't know, Jenny is named after our Vet. :)
