So I've housed Percy and Peanut together for about 2 years now. I have fleece in their cage with pads underneath. I sweep poops every day, but even then the cage starts to smell of urine w/in about 3 days. At the end of the week it is getting really bad and when I pull up the fleece the pads underneath are saturated with urine through out most of the cage, some spots being worse than others . I I thought this was normal, until I adopted Felix and Chewie about 3-4 months ago and set them up in a different room in a different cage. Right away I noticed that their cage can go for a full week without smelling at all. And when I pull up the fleece in their cage at the end of the week, there is about half as much urine on the pads as there is in the other cage. Which is obviously why their cage doesn't smell and Piglets and Percys does. My question is "Why would their be so much more urine in one cage vs the other? Cage size shouldn't be an issue as Chewie and Felix's cage is 4x2 fleece with a 2x2 "kitchen" attached that has carefresh, and Percy and Piglets cage is 5x2 fleece with a 2x2 "kitchen' with carefresh. So the stinkier cage is actually the bigger cage. Any ideas as to why my original two pigs are producing so much more urine than the other two? Or how I can make the stinkier cage not stink as much? I'm about ready to use fabreeze or something but I'm not sure if that's safe or not...
