Sophia if you knew how many times all of us have panicked over something you wouldn't be apologizing! LOL It's the mark of a caring, concerned snakekeeper so no worries there. Better you ask than blow off something that might be important. The panic does get better as you get to know your snake and be more confident in your own abilities to care for it but I don't think it ever really leaves any of us if something freaky occurs.

I know myself that if something comes up I have a few good experienced breeder friends on speed dial LOL. They are kind enough to have hand held me over the phone through the worries of our first breeding season here.

Back to the yawning though - do watch her on that. Excessive yawning can be a sign of something brewing RI-wise so mention that to the vet on your visit. If the yawning is related to shedding or just after they eat that's no biggie but if it's happening a lot at other times then you want to be alert to that.

If you got this snake from a pet store or from an unknown breeder then collecting a fecal sample to take in to the vet is a good idea. It doesn't generally cost much to get a fecal float done and it's well worth ruling out any issues of internal parasites (if the snake came from an iffy source). To collect a sample simply put some of her poop in a ziploc baggie and keep refridgerated - not frozen - and take it to the vet's office as soon as you can (you don't have to take the snake in with the poop - if there's a problem you can take the snake later for treatment for parasites). Generally a fecal float runs about $30.00 or less and some clinics will do it while you wait.
