Definition & Meaning of "flea circus"

What is a "flea circus"?

A flea circus is a type of entertainment where tiny fleas are trained to perform tricks or tasks within a miniature circus setting. The fleas are harnessed or attached to small props and made to pull tiny carts, jump through hoops, or do other small-scale performances. This type of circus is more about the unique and clever nature of the setup than the actual performance of the fleas, as they are hard to see and their movements are very subtle. Flea circuses are often featured in novelty shows, fairs, and historical exhibitions, highlighting the creative and whimsical aspect of the act.
