I know that grids at Target are about $17 for 23 grids, so that's not too bad. You could also check out garage sales to see if anyone has some used grids for sale. And instead of coroplast, which can get really expensive, you could use a shower curain (dollar stores have them I think) with lots of newspaper bedding or old towels/blankets for bedding. I hope you can convince your parents to get a C&C cage - it sounds like those piggies NEED a bigger home! Maybe try comparing the price of your store bought cage to the price of a C&C cage. So - if you make a 2x4 (or larger) C&C cage that uses less than 23 grids and you pair it with a dollar store shower curtain for a base, you've got yourself a roomy piggie cage for less than $20! Tell the 'rents that and see what they think!
