yesterday my cat started throwing up around 6am and done that 2 times in 30 mins. i didnt pay much attention since it was still active and playful in few hours he started being realy lethargic and apathetic and started hiding under the furniture. he refused to eat or drink since that morning. i took him to the vet, he did xrays and said he does not see anything blocking the intestines. he also took blood for filv, leukimia and pancreas tests since i also mentioned that cat started to loose weight few month ago and just before he got sick i weighted him and noticed that he lost a pound. so i might have 2 cases in one cat now and i dont know what do next. tests are getting expensive and im not sure how many i can afford. so far i have a cat that was slighly loosing weight over a period of few month but was still behaving healthy and playful and then all of a sudden he got sick, puking and loosing another pound and now refuses to eat or drink. vet gave him 200cc IV and a shot of antibiotics since he thinks it might be an infection in intestinces. any advice would be appreciated
