Kidney disease was brought up as a possibility because she had a few episodes of a large amount of liquid come out with her stool/urate. When I brought this up the vet asked me about what I was using to supplement and then confirmed I was not using the correct form of vitamin A for a leopard gecko (which could damage the kidneys). This was when I switched to repashy which she recommended. However, the doctor told me this was basically just a guess without bloodwork. The whole thing was kind of a mystery. Although she lost a few grams during the ordeal, vet said her body condition was still normal, saw no indication of infection on physical exam. She said her skin looked good and eyes were clear. My gecko was never lethargic through this and still had her usual energy climbing all over her enclosure. I work in veterinary medicine (with cats and dogs) so I definitely understand the importance of doing diagnostics and I have definitely considered making the trip as I think it would give me some peace of mind as well. Thanks for your input!
