The Animal Rescue League of Iowa a great deal of time rescuing over 70 cats and kittens from a Des Moines residents basement.

ARL workers say they even found some of the cats dwelling in the walls of the home on Tuesday. Rescuers referred to the scene as 'gruesome.' Some of the cats are pregnant, two had deformities, and others are critically ill.

Veterinarians are examining each rescued cat, one of which needs immediate surgery to save its life. Sadly, four cats have already died.

Crews went back to the home yesterday, Wednesday, in an attempt to rescue more cats.
