Tasha spent Wednesday night and most of the day Thursday at our vet's animal hospital. They wanted to continue treatment with medication, etc., and hydration, do more blood tests, another x-ray, and observe her. After this round of treatment our vet still doesn't know for sure what's going on though he thinks it may be either inflammatory bowel disease or (worst case) an intestinal cancer (lymphoma). We have a cat who looks and acts well except for this nasty symptom of throwing up just about anything she eats. Now she's been through about 48 hours of stress and it shows. We fear the high stress could activate her FIV and cause even worse things to happen. It's so frustrating! We're doing everything we can for this kitty and still we don't even know for sure what is going on! Tasha came home last night (Thursday) and spent a lot of time exploring the entire house. She still seems a little ill-at-ease today but is becoming more relaxed. I'm to dose her twice daily with oral cortisone and antibiotic medications. My plan right now is to offer her very small bits of food, which she seems to tolerate, during the day in hopes that we can get her system running normally again. I'm to call the vet at noon and speak with him about Tasha's condition and what's next.
Update: We'll continue medication and attempts to feed Tasha over the weekend. Next step in trying to solve this mystery, if symptoms continue, is to get an image using barium orally to see if it discloses a kink or invisible blockage of some sort that is causing this trouble. We'll see how things look Monday.
