Andrew Weber: This is just in one room on Vozrozhdeniya Island. A piled up, hundreds of animal cages, now. We saw one cage that was large enough for humans. We expect that large non-human primates, like baboons, were probably stored in these cages. But they would take the cages out to the test site and then expose them to biological agent. This was probably either small monkeys like macaques or rabbits, small, smaller animals. Oh, and yeah, this is actually a younger me standing next to this large cage that we found on the Vozrozhdeniya Island laboratory complex.
