There are a few symptoms to RI beyond a couple sounds. I am not a vet, however that alone is not enough to make me take an animal to the vet. Do some research on RI. I would expect some mucous issues. I have one snake that has made RI like sounds every time she is picked up since the day I got her and there is nothing wrong with her. I would also look at probable cause. If the animal is being kept properly, there is a far less likely chance of it having an RI. The snake could be burrowing to get closer to heat. The OP says that they got the snake a couple weeks ago. I would ask from where and how are they keeping the animal. There could be husbandry issues. If that is the case the likely hood of RI goes way up. In short, OP, we need more info about how this animal is being kept and if you are seeing more symptoms than just the sound. Please take a look at this and see if you are meeting the requirements of the animal. If you are unsure then by all means go to the vet but it will not be a cheap visit. It you do visit a vet make sure it is a reptile vet. Many vets don't know squat about ball pythons.
