Albino laboratory rat (Rattus norvegicus) feeding inside a metal pipe. Albino rats were bred from the original brown Norway rat for use as experimental test subjects. They are now one of the most common mammals used in animal experiments. Their size and physiological similarity to humans makes them ideal subjects for medical and toxicity tests,whilst their intelligence means they are often used to test behavioural theories. However,the suffering caused to animal subjects by experimentation remains controversial | |
