A potential issue is affecting Texas animal shelters, which are already crowded. The New World screwworm is a concern, with possible implications for these shelters. The Houston SPCA is taking steps to protect animals in their care, such as providing horses with fly boots to safeguard their hooves.

This is because horses' hooves are vulnerable to wounds due to exposure to the elements. Further details about the New World screwworm and its potential impact on Texas animal shelters can be found through the Odessa American or other sources, including the Texas Tribune.
