: 0 Hello cute piggy owners!! As of lately my 12-13 month Piggy has been making this noise (I’d say this is the 4th/5th time I’ve heard him do it) most comments on YouTube say it’s a sneeze or cough. I also notice he’s been resting more lately when it comes to feeding time, however he does still come out, just a few minutes later than my younger piggy. He also makes mumbling (deep wheezing noises) while eating his hay. I also tend to notice small bits of crust around his eye sometimes (looks like eye boogers) but his eye has always appeared clear. Just as a side note my house is on the colder side, but we do turn on heaters from time to time. Could this be allergies or sickness? Or is this normal for Guinea Pigs? Thanks all. *NOTE this is NOT my video and all rights reserved to original owner. Just using this video as an example since I was not able to get audio of my own pig.
