What percentage range of animals used in biomedical research are rodents?

Explanation:
Rodents are the dominant group in biomedical research because they are small, inexpensive to house, breed quickly, and have well-developed genetic tools that make it easy to create disease models and study mechanisms. Because of these advantages, mice and rats comprise the vast majority of animals used, typically around 90-95%. The other ranges would imply a much larger share of non-rodent species, which does not align with how most research programs allocate animal use.
