There are loads of guineapigs that need adopted,
why make more homeless, poor souls? Why must you breed them? The last time i saw a litter of guineapigs i felt like crying my eyes out, One was only born with two legs, one with 6 legs, one blind, two death!
Only 2 survived, and they are very weak still.

Adoption is the key to happy piggies,

Breeding could kill your sow, please recconsider.
