28. At some institutions, violations were repeated, but federal oversight authorities took no meaningful corrective action. Some incidents reflected pain and suffering for many animals. For example, in just one of 60 incidents at the University of Minnesota, 75 rats were used in experimental surgeries but were given no post-operative pain relief. In just one of 53 incidents at the University of Pittsburgh, 83 pairs of mice were surgically joined together via parabiosis without analgesia. In one of 39 incidents at Yale University, a mouse rack with 141 cages was found disconnected from the automatic watering system. Eight mice died from dehydration, another had to be euthanized, and 93 were found hunched and dehydrated. At the University of North Carolina at Chapel Hill, 11 mice starved when workers did not feed them. At the University of Michigan, tumors in mice were not adequately monitored and were allowed to exceed the protocol endpoint limits—increasing the pain and distress suffered by the animals. A rat who had not been euthanized properly at the University of Michigan was found dead at the bottom of a cooler after having chewed through a bag.
