So my big Leopard has been.... well I'm not sure what to think of it but seems like she would sneeze once in a while... or wheeze. When I first got her back in ... August she always had a running/bbubly nose once in a while. I would probably say once a week or something. I don't think it's RI but I could be wrong since my other leopards don't have any issue with runny nose or breathing funny. It started off with some hard wheezing but lately (its been a week) she would occasionally sneeze or just sounds like a release of air. Every few hours or so. No behavior has changed... still bask under the light and gets excited and eats and poops and curious on what I'm doing and such. The only thing I can recall I changed was I've been adding that TNT powder but... I used it for a week with no change and lately I've stopped using it for a week and the symptoms haven't gone away. I also noticed she has no more runny nose or bubbles which is good I suppose? I forgot to mention, she doesn't breath from her mouth or anything either and for the most part acts normal. I've changed the substrate thinking it may have been something from the mulch but no change on her.... just getting concerned and what I should do at this point.
