i love my piggies! one of them coughs more than once, every day. it sounds like he's choking! i got him recently and didn't realize that the bedding that his previous owner was the Carefresh stuff. Could the coughing be the result of that kind of bedding? I stopped using it and i'm using this natural pine bedding, but he still coughs. I asked about this before, but someone said that it was ok, as long as it didn't sound like there was any fluid. it doesn't sound like it, but I got a new piggie and he doesn't ever cough the way Tootsie does.
