Cage size matters for ammonia levels

Housing laboratory rodents in individually ventilated cages (IVCs) improves the environment of both animals and lab personnel, but ammonia build up might go undetected in IVCs. In a new article, Eskandarani et al. sampled mouse IVCs in their facility for ammonia levels. They found that smaller Type II IVCs accumulated more ammonia than larger Type III IVCs, with several Type II cages showing ammonia levels > 50 ppm.
