I live in Philippines, and do you know any vet near Quezon City and can handle guinea pigs? reply ASAP and thank you 
Oh i'm so sorry let me translate it i have a guinea pig his name is yum-yum he was 2 years old now i notice that he didn't eat too much and i also notice the wetness of his mouth i don't know what to do i'm afraid to loose himplease help me i don't know what's happening to him.
last october we just notice that he didnt eat too much but now it still the same and we notice that he has a wetness under his mouth and he has a smell and he is just standing not lying. Help me guys i dont know what to do my mom and i carefully forced him to eat and he it. We also visited 5 vet but they just know how to cure dog and cat.Your original post about yum-yum was last October, is he still ill and you haven't found a vet yet?
Do you have a zoo near you? They would have a more experienced vet.
