Ok, so after reading the first reply I called the vet and took off with Safir. I was seriously freaking out, and I didn't wait arround any longer to see the replies.
I picked up the plastic bag where I threw the paper towels used to clean his vomit got Safir and drove to the vet.
So, she did an thorough examination on him , took blood, fecal sample, and took a look at the vomitus I had brought with me. It was definitely blood mixed with bile. He didn't have any discomfort when she palpated his stomach. And he didn't seam to be lethargic anymore (he was a little after throwing up), he was actually happy to see everyone there. She thinks it's a stomach ulcer
, possible from food allergies. Fecal sample was fine. We are waiting for the blood results. Meanwhile she gave him 2 injections: one to stop the vomiting, and one that coats the inside of his stomach with a protective layer. Also gave me some tablets to give him.
Poor Safir is exhausted. He ate just a little tonight and is now resting.
I think starting tommorrow I will cook for him light food (boiled chicken and rice, or sweet potatoes) until he gets better.
Thank you for all your replies, and if you have any other advice for me, please tell me what else I could do to help him feel better, because it breaks my heart to see him ill
