While doing the weekly deep cleaning yesterday I realized my yearling pearl burmese might be developing a respiratory infection.

While once out she's sweet she still hisses a lot when first picked up and the first hiss sounded "bubbly". Indeed she had a few mucus bubbles right where she sticks out her tongue. The mouth looks almost clear. No wheezing sound, clicking or any other sign.

I've already moved her to the warmest spot on the rack (she was on the bottom which stays around 87 F). I'm also making sure humidity stays higher with a brief spray twice a day (she does NOT line it lol).

Besides raising temp and humidity what else can I do?
Brian Barczyk suggest using a fogger with F10 to treat mild RI in this vid https://youtu.be/pJCnPfuqaBM and if I can find the damn product I might try. Is it something widely used?

I have a 24/7 specialized vet close by and will take her in if it persists or gets worse.

Thanks

PS: old picture but that's her
