This hardware cloth has holes that are only 1/4 inch to keep critters out and the chickens/rabbits safe, and protect your garden fruits and vegetables from rodent animals. The 1/4 inch openings would have to be really small to get through. Use to keep out small critters such as voles, gophers, snakes, racoons, etc. out of your property. The wire is sturdy and galvanized making it last a long time.
