I have an 11 month old F2, Echo, who started vomiting a day and a half ago. He threw up three times. I took him immediately to the vet yesterday. They did x-rays checking for blockage in the morning, and I brought him back yesterday evening to do more. It looked like it was moving through. He ate a small amount last night, and continued to drink. He did pee in his litter box. He has not eaten anything today and we are back at the vet. They are doing another x-ray, giving fluids, doing blood work, and giving him an anti-nausea medication. Is there anything else I should ask for? I didn't see him eat anything that could cause a blockage, but I don't know for sure.
