amcashes - keep an eye on the girls for signs of URI and please, if you suspect a URI in any of them, get them to a vet immediately rather than hoping for a home remedy and waiting until it's possibly too late to get them to a vet. Having "only two" of the symptoms of a URI isn't sufficient cause not to have it checked out by a vet asap. Trust me, it's better to be out the exam fee and not have a URI than to wait too long to get them in and be facing a much more serious infection than if you'd reacted promptly.
If you got medication to treat for lice, please do treat the girls too. Lice and mites are easily transmitted from pig to pig (same cage or not) and treating them if they don't have lice/mites won't hurt them.
I want to remind folks that the ranking system is in place to let people know whether or not their posts are helpful, not to vote posts up or down based on personal vendettas or previous experiences with certain members. Please keep that in mind the next time you want to rank something down simply because you aren't a fan of the member posting it, whatever the reason.
