* Individual Variation: Like any species, rabbits have individual differences in size, health, and speed.
* Lack of Standardization: There's no standardized test or competition to measure rabbit speed.
* Environmental Factors: A rabbit's speed can be affected by factors like terrain, weather, and health.
However, we can look at some general information about rabbit speed:
* Average Speed: Most healthy rabbits can run at speeds of up to 35 miles per hour in short bursts.
* Slowest Breeds: Some rabbit breeds, like the English Angora and the French Lop, are known for their more laid-back personalities and may not be as fast as other breeds.
Ultimately, it's impossible to determine the slowest rabbit in the US without specific data and observation.
