Cat cage, made of metal. Can be configured as 2-tier or 3-tier. Assembly type. No tools required. Since there are no instructions, I will enclose instructions for a similar type of cage. (The assembly method is the same type) I used it for about 2-3 weeks when I got a new cat. I have cleaned and disinfected it, but there may be some fine hairs remaining. Please purchase only if you understand that it is a used item.
