We've had our 3 female piggies for about a month. Their cage has been expanding since we got them - they are now in a 2x7 C&C cage. So I changed their bedding today in the whole entire cage, and they smelled fresh until the afternoon. But by the evening, the whole family room (where the cage is located) smelled like...piggy. It's not pea/poop, it's just the musky but strong smell of piggy "B.O." I wouldn't mind it, but my husband has a VERY sensitive nose to animal smells, and he is hating it. Not sure what to do? I put aspen bedding...did not use any Carefresh this time, as I am trying to "wean off" it - for a big cage like ours, it would be too pricey for the long term. I might sprinkle some Carefresh in the cage tomorrow, hopefully that will help a bit. Any advice would be much appreciated!
