Eliana - I don't think anyone is saying that you do not love your pets, or look after them well, but it does sound like you don't fully understand the big picture.
You say you let your piggies breed if they want to. It isn't a matter of wanting to - it is a matter of instinct. Nothing else matters where instinct is concerned, eg whether or not it is the right thing to do, safe, etc. When your female comes into heat the male will instinctively try to mate her. If she doesn't "want" to mate she will try to avoid him - but he will keep pestering, effectively trying to force himself upon her whether she likes it or not.
Animals also couldn't care less about inbreeding (incest!). If you leave the males and females together they will all attempt to maet with eachother. Mother to father, brother to sister, mother to son and father to daughter. This is VERY bad - inbreeding is known to cause all sorts of health problems. Not to mention you could quickly end up overrun with guinea pigs.
Even proper breeding - no inbreeding, healthy pigs of the correct age etc. is risky. It is estimated that 1 in 5 sows die. We dodn't pick this figure out of the air - it is fact. The breeders themselves are aware of this. They know they can expect high losses and they accept it. Can you?
You say there is no problem with piggie overpopulation where you are. For the time being maybe. But what is going to happen if every piggie owner acts like you and lets them breed freely? More and more piggies. It won't be long before there are more piggies than homes. Have you thought about what might happen to these unwanted babies? There are no shelters you say - which means they will either be euthanised (at best) or simply killed or turned loose to die on the streets.
You clearly have no idea about neutering do you?
For a start, in many species neutering (particularly spaying the female) prevents a whole host of potentially fatal diseases, such as some cancers.
In males of many species it can reduce behaviour problems such as aggression, allowing males to live paecefully together rahter than having to live in solitary confinement (eg rabbits - not piggies though).
Neutering also prevents unwanted pregnancies.
In the hands of an experienced cavy-savvy vet neutering is a routine procedure unlikely to cause your piggies any problems. They should be fully recovered within a few days. Pregnancy on the other hand means weeks of carrying round a belly full of babies, a painful birth, and potentially deat for both mother and pups.
There is every possibility your other sow died as a result of complications from her pregnancy and birth. Not necessarily - but you can't rule it out. Then again, it could simply be because she was a store bought pig - pet stoers are notorious for selling unhealthy, badly bred animals riddled with parasites and infectious diseases.
i dont want any ansewrs i know what is good for my pigs
