I googled bezoar and it said it's a hairball but the vet didn't see anything on the x-ray except the one spot and she said it looked like stools but wasn't 100 percent and the ultrasound is the next step.

Honestly i'm struggling with money right now and I need to see if it's something simple. My husband hasn't worked in almost 3 weeks because he is sick and I have already spent $200 for my kitty and it's another $150 just for the ultrasound.
