Change in Guinea Pig Noises

Question
Hi, I was wondering whether you could advise me on a new noise one of my Pigs is making. I have noticed that she is making a grunting/squeaking noise - it sounds very nasal - almost as if she has a cold. I have never heard this before as she usually 'squeaks' normally. She hasn't lost her appetite but i am worried she may have a cold. Do you have any ideas?
Thanks
Lucie

Answer
Hello,
Have you ever heard a child moaning because they don't want to do something, this is the sound of the troat moan, it is most commonly heard when one guinea wants to be alone while another or a human wants to snuggle up to it.
I fhtis is not the case then keep your guinea warm and dry and consult your vet.
Best wishes
