Laxatone Substitutes: I read that petroleum jelly is okay, how about mineral oil? I know this is used as a laxative for humans, and my ferrets LOVE it. (I discovered this when I was trying to clean their ears with it.) Corncob litter: I had the new baby using this, and the other day Louise ("The Terminator") made a surprise attack. I guess the stress brought on what was inevitable - the baby started puking. In my total panic over what might be causing this, it took me a few minutes to realize the puke was too light to be used Iams. A lightbulb went on over my head - THE LITTER! Changed the litter and she seems okay. While I don't know if the litter could cause a blockage (it looked pretty much paste-ified) I'm sure this delicacy is not good for the fuzzbutts. Watch out for culinary experimenters! [Posted in FML issue 1635]
