Tomcat Courtney, who had to use a respirator as she fought off the gas from the chemical spill, said she was glad to be home.
“It’s kind of like being back in a warm bed,” she said.
Tomcat Bromethalin was also happy to be back in the lab after being away for a month, but was more hopeful about her future.
“I’m really excited to get back in there and do the work, and it feels like it’s going to be more fun,” she added.
The Cornell University Medical Center said that after Tomcat’s inhalation of the chemical, Bromethal and its analogs, such as Roxan, had been detected, the chemical had been declared a probable carcinogen by the National Toxicology Program.
The university’s Environmental Science and Technology Center (ESTAC) was able to isolate the compounds and determine that they were potentially toxic to humans, as well as animals.
It also identified two other compounds that were not related to the gas and had not been previously detected.
Tomcats and other animals at Cornell have been allowed to resume their normal activities, and the university is looking to reopen the school in April.
But a release from the medical center stated that Tomcats are no longer allowed to perform certain activities.
Cornell said it would work with the US Fish and Wildlife Service (USFWS) and the US Environmental Protection Agency (EPA) to ensure the safety of Tomcats as they work to prevent and mitigate the risk of a chemical spill.
The chemical was found in a large tank of a Cornell facility that was used to store wastewater at the time of the spill.
TomCat’s first exposure to Bromethali occurred at the University of California, Berkeley, in the spring of 2015.
The University of Tennessee-Chattanooga in February of this year reported the first detection of Bromethals at the university’s wastewater treatment facility, which is owned by Cornell.
Cornell is investigating the spill, which caused an estimated $2 million in damages.
