Hi, I hope this information will be helpful; it has to others with females I know of that have had this same condition. DF
From Merck Veterinary Manual:
The 'cheesy' discharge is Candida from being in heat, yet as noted above often contain bad bacteria forms Our Vet said this is vaginitis, not a UTI where you see evidence of blood. This cheesy discharge that gets thicker towards the end of the heats, gently pressed laterally above the urethra towards the opening helps to expel the cheesy discharge and keep the orifice open. Our girl had this for years during her heats, that as the vet told me would get longer and harder as she age, as is common to rodents. Then all we had was AB, yet they didn't support her immune system to counter these common bacteria during or after treatment. I knew a person with a female squirrel in the UK that tried treating this condition initially with Soil Based Probiotics that resolved this same condition.
In plain language, this Veterinarian explains in this article why SBO are needed to counter bad bacteria, with over 70 percent of the body's immune system is located in the gut.

In the wild, tree squirrels obtain good bacteria from ingesting soil; this most commonly is observed when squirrels pull up the tufts of grasses and flip them over to chew on the soil that surrounds the roots that also provides them with a key source of calcium and other minerals and a source of good bacteria that limits the overgrowth of bad bacteria in their gut, which contains over 70 percent of their entire immune system. SBO included in the diet provide a vital replacement of this component which lends significant support to their immune and digestive system in captivity.

Should this or no other SBO is available in the UK, or you can't order it from the US source, let me know; I may be able to send you a bottle to support your squirrel.
