These new cages are 18X30 and 16 inches tall, I needed another small cage to seperate started chicks into when I am getting them ready to go to thier new owners. And I also needed one more cage for the same purpose with Baby Rabbits. I really liked these cages because the sides and top are made with 1X1 inch wire and 1/2 X 1 inch floor wire. MAY 13, 06
