Howdy all! I read this in Tuesday's FML: >>>1) Dr. Williams has said to watch for tooth-grinding as a tip off >to ulcers. I am watching Slinky closely, as I just introduced these >two into the same cage. Does this mean a horizontal gnashing of >teeth?... I know what I am looking for. I have a ferret that recently has started to gnash her teeth... I couldn't figure out why that would be... An ulcer could be a possibility, since she did stop eating for a couple of days just before I noticed her new habit... What I would like to know, if she does have an ulcer, is there anything I can do about it? My roommate had an ulcer once, and it was so bad that he had to have surgery. Are there any non- surgical cures? On a different topic, I also read this: >>>What is it specifically about clay-based cat litter that is harmful to ferrets? I am also interested in this answer, since I have always used scoopable cat litter. If clay-based cat litter is harmful, what are some alternatives? Thanks. Jeffery A.
