My black cat Harley made a mess in my floor. Before I could positively identify what this mess was my mind thought he has pooped in the floor . Come to find out it was car hair shaped like turds would be. They were covered in undigested dry cat food. Why did this happen? Is it normal to be this shape? I always thought hair balls would be ball shape . Sorry for the graphic details but I'm worried about him. He will be a year in August.
