grunting noises ?

Question
pigley is making a noise i think shes pooing &shes very skinny please help  thank you

Answer
Guinea pigs do make noises naturally, see: http://www.jackiesguineapiggies.com/guineapigsounds.html

They must poo and tend to poo extra well scared or stressed.

Take her to a vet if she stops eating but for now just feed her more treats and make sure she has a good regular food.

Thanks for aking,
