Symptoms of disease help please

Ok so my 876 gram spider is ok eats but I have noticed twice this happening sometimes she will hiss and breath in and out very deep if she gets mad at the food I offer her. And, when she does this I notice some bubbles in the front of her mouth, however there only there when she does this. I checked her gums no extra saliva or bubbles is this normal or the beginning stages of Respiratory infection? Thanks kindly for the help

Since you haven't seen any other symptoms of a Respiratory Infection, it's possible that she had recently drank water before you offered the prey and that is what you were seeing. Were these two incidents successive or occassional?

The best that I can offer is to keep a close eye on her for any other symptoms:
-Wheezing, popping, or the sounds of congestion when breathing.
-Mucus in and around the mouth and nostrils.
-Dried mucus on/around the sides of the enclosure and furnishings.
-Excessive face rubbing.
-Constantly keeping the head elevated or stargazing.

thank you kindly for the help
