True or False: Rats and mice are considered covered species under the PHS Policy for Humane Care and Use of Laboratory Animals.

Rats and mice are indeed considered covered species under the Public Health Service (PHS) Policy for Humane Care and Use of Laboratory Animals. This policy applies to all vertebrate animals used in research supported by the PHS, including those used in federally funded research projects. The inclusion of rats and mice under this policy reflects a commitment to humane treatment and ethical standards in animal research.

The rationale for covering these species stems from their widespread use in biomedical research, as they have greatly contributed to advancements in science and medicine. Recognizing them as covered species ensures that they are afforded the same protections as other laboratory animals, fostering a culture of responsible and ethical research practices. This underscores the importance of adhering to regulations and guidelines that promote animal welfare and ethical treatment across all species used in research.
