Coroplast Base for a Midwest Habitat Guinea Pig Cage by Cagetopia

Coroplast Base for Midwest Habitat Cages

This Coroplast base is made from 4mm-thick corrugated plastic and is designed to be placed on the INSIDE of the Midwest Brand (and their knock-offs of the same size) wires. This size is 22.5" x 46.25" and replaces the NON-waterproof, canvas base of that cage. It is professionally cut and scored and includes reusable, plastic rivets to secure the corners. The "canvas" is not not truly cleanable and leaves trapped bacteria harboring smells and worse. The wires are not attached to the Coro base, but it's not necessary as the rigidity of the Coroplast keeps it in place.

The wire fencing is NOT included.

Midwest Cage Replacement Base

On the 10" wall option: We do not make cutouts for the two 6" openings because the six panels are interchangeable and can be configured in multiple locations.

The 10" wall option is not returnable.

22.5" x 46.25" Coroplast base replaces the original canvas base. No velcro straps needed; sits right inside the original fencing. Flaps fasten with rivets. All plastic, easy to clean and maintain.

Coroplast Base Includes

4mm Coroplast bottom in your choice of 16 colors!
The base is pre-cut and pre-scored with pre-punched holes to secure flaps using snap-in plastic rivets (not tape). Coroplast base is creased and folded for shipping, which creates an indented "crush" line. This does not affect the functionality of the cage and is behind the grid wall when assembled.
Rivets for fastening all coroplast flaps

WIRE fencing is not included.

The raspberry Midwest cage bases are super cute and really easy to put together! Hoping they’re also durable :)

Coroplast base

The base was perfect for my Midwest habitat. The Midwest cage purchased needed additional support- only had a canvas bottom. My guineas are safe poppinh on a strong bottom. 🤗

This is my 3rd time buying g these wonderful liners. I highly recommend them for people, like myself, who have the Midwest cage set up for their fur kids.
I have found that they stabilize the grids and are a lot easier to keep clean.
