Well, I think the mice are recovering. If I just stand beside the cages, I usually don't hear anything at all, but as soon as I reach in to do anything, I guess they get a little excited and start sneezing again. If I pick them up to listen more closely, most of them sound like they are breathing clearly, but a couple still have that rattling squeaking thing going on. I think it is not as bad as before though. The one male is still the worst; he probably just has a weak system so I may feed him off rather than using him for breeding stock.

I decided to try giving them echinacea. A bottle of tincture was only $7 at GNC, and I decided that as long as I didn't overdose, it couldn't hurt and might help. Of course, now I have no way to know if it helped or if they would be improving by now anyway. I added it to their water, 5 drops per ounce, which was a mistake. I intended to base it on the amount mentioned in the article I linked above, but that is 2.2 drops per ounce, and somehow I confused myself. I will adjust it to the lower amount, but it does not seem to be affecting them negatively at the higher dose for the short time. Also, the article is talking about rats, and I know the dose needs to be smaller for mice, but I'm sure mice also drink less, so it should even out. I am watching closely to make sure they still drink about as much as they were before (in case they don't like the taste of it and might dehydrate themselves), but so far I can't detect a difference.
