Christa,

As for finding objects on X-ray: when our vet performed an X-ray on Callie they didn't find anything and actually said her bowels looked normal. When they did the ultrasound, they did find a shadow in her stomach. The only reason they went on and did surgery was because she continued to vomit despite everything they gave her.
I will pray that Brodie turns out to be perfectly find. Callie is doing quite well and I will be updating everyone in another thread with pictures! Take care and let us know as soon as you know something.
