sick guineapig

Question
my guineapig sounds like he is weezing when breathing and sneezes an when he does white stuff comes out. please help me.

Answer
most probably this is a respitory problem, if you use sawdust then please stop, shake hay well before placing it in the cage/hutch so there are no dust particles. if you keep him in a humid or drafty place then move him to somewhere still warm and dry. hopefully he will over time begin to show signs of getting better, if he shows signs of it getting worse then i would get him down to the vets pronto.
