0] Hi, i just got a guinea pig for christmas this year and i got a small cage that is (i think) way too small and i need some tips on how to make a C&C cage, i need a bigger cage because my guinea pig just had a baby and it will grow up and be to big for the cage i have now so if you can give me any tips then that would be great! thanks0]
Just look around https://www.guineapigcages.com . There are a lot of examples for cubes and coroplast cages. There is also a database on the front page so you may have been luck finding the supplies.
Also check to make sure the mama and baby are the same sex.
