Clean it off.
no, more
I try to clean my guinea pig's cage around once a week or when it looks dirty.
No, it just means that you are feeding the guinea pig too much. I have a guinea pig that had the same thing, but now that I feed him less. Like I said before, your guinea pig should be fine. Another reason why might be because they poo more when they are frightened or scared. I had the same thing.
Wont eat or talk. Or poop.
Yes because there is the after birth from the guinea pig
Guinea pig most likely does the exercising when running around. i would suggest you get a wheel from you local pet store for the guinea pig to run in or you can just do what i do and close your room door and let your G.P. run wild, although only attempt this if you have the energy to clean as G.P. make alot of poop.
Both male and Female guinea pigs sometimes eat their droppings. the reason is that their poop contains minerals that are helpful to the guinea pig.
once a week
you clean it
THIS IS TRUE! they are trying to poop but the poop wont come out.
Either leave it, it should come off in the sawdust or wood shavings, whatever is in your guinea-pig's cage, or, you can pick up the guinea-pig and flick it or pick it off.
