QUESTION: Hello. i checked the other boy and the other one is now Limping i think he has broken his leg!!!!?? And anther Question Well I went to my friends house to go see her guinea pig and then she left it out in the sun and then when we went to go take it inside i picked it up and it was so weak it could'nt stand up or keep its head up  then i rushed it to the vets they told us to put a wet towl around it we did and put ice blocks trying to get it cool we did as much things as we could then it started to breath slowly and slowly and it kept opening its mouth while breathing then 5 min later it stoped and died i was very sad then after when it died its eyes started to get all wet and the white bit started coming out why is that.

ANSWER: Hello again.
I honestly dont understand why people do these things. Letting you guinea pigs run together is fine but leaving it out in the sun is just stupid. The poor baby died of heat stroke and it was in extreme pain when it died. The white stuff was a combination of the body getting rid of waste and toxins after death and the piggy crying because it didnt understand why somebody would do such a thing.
Also, your guinea pig is in severe pain and might stop eating. Yes this means it could die.
Take him to the vet to get a cast, and look up how-to-be-a-good-owner for your friend.

Answer
Hello again.
I am sorry as I know that reply sounded harsh, but it was nessisary to my part.
Unfortunatly, heat stroke is a common cause of guinea pig death, and is completly avoidable. Its like when people die of starvation and aids is 3rd world countries.
A vet would have advised you to think about putting her down, and he would have put her in intensive care. I doubt she would have made it though, her blood was already too thin.
