From 2015 to 2018, over 601,218 animals were used in research or 'humanely killed' at King's College London for scientific research. The most commonly killed animals were mice (458,339 in total) and fish (178,886 in total).

The College has published a full table detailing all of the animals killed and used in research between 2015 and 2018, which can be found below:

The university has also provided some information on how and what they use these animals for prior to their deaths, classifying their use into three categories.

Animals used for scientific procedures

"These are animals that have been used for experiments under the authority of a project licence. Only individuals with a personal licence are able to carry out these procedures. All genetically altered animals (inclusive of mice and zebra fish at King’s) are included in these numbers, even if they are used for breeding or for tissue only. Many of these genetically altered animals are assessed to have undergone mild or no suffering."

Animals used for breeding purposes

"Some animals are housed at King’s for the sole purpose of breeding (mice, rats and fish). Healthy rodents are allowed to have up to 8 litters during their life span. All rodents used for breeding purposes are humanely killed after their final litter has been weaned."

Animals used for tissue only purposes

"Animals that are used for tissue only purposes are housed at King’s, but are humanely killed without ever undergoing a scientific procedure. Tissues are collected from these animals and may be used for a variety of purposes from cell culture to isolated organ perfusions. Where possible, animals will be used for tissue only to reduce the number of live animals that undergo scientific procedures."
