Hi, gui.pig. You won't be asked to leave the forum if you breed, but you won't be allowed to discuss breeding or ask questions about it. We are a strongly pro-rescue forum.
I know a lot of people think it would be nice to have baby guinea pigs, but do you know that one out of five sows dies giving birth? And that a similar proportion of the pups are stillborn?
Do you know what a roan guinea pig looks like? or a dalmatian? Do you know what a lethal white guinea pig is that can result from breeding either of those? They're born blind, deaf, either toothless or with very poor teeth and require handfeeding, and have severe intestinal issues.
Do please separate your pigs and do your research carefully before proceeding with this. There are literally thousands of guinea pigs in rescues and shelters than need good homes. There's no need ever to breed another guinea pig deliberately -- enough are born from accidental matings to more than keep up with the demand for them.
