chlorhexidine is a very good for killing bacteria and fungus. Most dental offices carry chlorhexidine mouth rinse. You certainly wouldn't want to drink it, but the little bit that would remain on her foot wouldn't be harmful to her if she licks her foot later. You could wet a cotton pad with it and hold it on the foot for as long as she will tolerate it. As well, if you want a totally natural laundry detergent you should check out soap nuts. You can purchase them on Amazon or your local organic grocery store. Hopefully everyone is better soon!
Another excellent natural, gentle cleaning substance is soapwort. It was used in Europe before soap nuts were imported. Soapwort is recommended for washing face and hair, and also for washing most delicate fabrics like silk or wool. https://www.mountainroseherbs.com/products/soapwort-root/profile
Soapwort root pieces need to be boiled in water. This soapy brew is then used for washing or bathing.
The nicatin cream is not working as well as we like. It is helping the fungus, but not making all of it go way. We might try the chlorhexidine. One other question is do we actually really need to treat it? My gps don’t seem in pain, are there any bad long term effects of having fungus in their feet?
I'm not sure if Pigsy has a UTI. This afternoon I was watching them play in their cage, and Pigsy went to the littler box to go to the bathroom, and I noticed her pee was a dark colored. I'm not sure if it's normal, it looks orange/pink. Do you think it's a blood/UTI or normal?
