Rats make lively and wonderful companions and are best kept in a group. Unfortunately rats are disparaged in our community because people are afraid of them or view them as unclean.
Rats are used by the medical community as ‘lab rats”. Basically they will live and die having tests performed upon them, often without any pain relief. Many of these tests are unnecessary and outdated as it has been found that rat responses to medical trials are often very different to human reactions.
