Regius_049’s reply is awesome, I may look into the tests you linked there. My vet said the IBD test is $400, which is the only reason I (a student with a part time job) haven’t requested it yet.
I was wondering if any of you had input on whether that seems right? It looked like that void panel test was a fraction of the cost... and understandably if there’s an option that’s less daunting I’d love to act on it quickly!
