Hi Dale
Welcome to the forum & congrats on Scott's new companion
& good on you caring enough to look for info!
First of all... have you been to: <a href="https://guineapigcages.com/" target="top">cavy cages</a> which is the base site for this forum
The site tells you everything about C&C cages, how to make them, where you might find the materials, dif things you can do to individualise the cage & <em>stacks</em> of pictures!!!!
C&C stands for Cubes & Coroplast as they are made of Cubes (as you know
) & Coroplast, which is a hevy duty but lightweight corogated plastic sheet that is known for use in signs & display boards (In Australia most of the Real Estates use it for their "For Sale" signs). But it is starting to become popular for other uses (Cages!!!
, Packaging, Model Aircrafts, Pushbike baskets/shields)
Coroplast is actually the name of the product when it comes from the <em>Coroplast</em> company! You also might find it under another name... Corflute, Coroflute, Cadflute, Fluteboard, Correx, Corex, etc... If you look at the pictures & get an idea of what it is & what it looks like you can identify it from another company by another name
<a href="https://www.loomisandtoles.com" target="top">loomis and toles</a> is aparently a net art supply company that delivers in Canada. Or try your local sign making company, plastics company, art/craft supply store, Home-Improvement store, glass store (they might use it as packing between the glass!), or even a second hand piece from a real estate agent! Or seach the net for "Coroplast" (or other names) or "Plastic" (for a plastics company that might sell it). & when you do find it... please come back to cavy cages & put in the details of where you did so others can find it too!
Good luck on finding your materials & have fun making your new cage
& all the best luck with caring for your son's new friend
