Technically a good photo, would have been much more powerful if you included one of the animals. At the same time, for the animals sake, it's good to see them empty.
Not sure if most people would be familure with an animal testing facility. L()L.
It is an interesting image, but not sure it really tells me what you do, or do most the time.
Haunting and so much is said by so little. I think I would have liked some post processing in this...warmer, more ominous lighting... just my preference though.
