Hello,
So sorry that Pudgy is having all of these problems!
She must not be feeling well. Did you already post pictures & I missed them somehow? Sorry!
Would you happen to know the concentration of the Fortaz? What is the dose she is getting, every 3 days?
As suggested, diluted betadine or novalsan is very effective for cleaning the mouth area. You can use a swab & dip it into the diluted solution & run it along the mouth & gum areas to try & clean it out. Could it be retained shed, or not?
I honestly feel that the bad lighting is probably what triggered this, as it suppresses the immune system which snowballs into other problems.
Her fecal was clear on the last checkup?
The breathing could be the initial start of a respiratory infection, or it could be frustration such as what they exhibit with the forced exhalation when they get mad or have temper tantrems. However, you don't want it to go unchecked just to make sure since you mentioned that she never breathes like this. When she breathes, does it appear more labored than usual?
Do keep her tank around 80 at night, or place her on a heating pad on low, to keep her warm & help her immune system.
As far as her going potty in the middle of the night, etc, that is not normal no, but, can be normal when on harsh medications such as the Fortaz. Are you giving probiotics & extra oral fluids right now?
