Adopted my now 7 yr old cat when she was 2 months . she was tested + for FIV and since her adoption hasn't had a spell, just about 2 weeks ago her health has gotten bad , 1 week ago i took her to vet he said its possible she may have FIP. Since her being sick the 2 weeks she has gradually lost appetite to no appetite and no drinking water. Vet gave her medications, obtrax , neutrical and tansfor factor . i took her this monday for recheck since he said he is dehydrated she seems to drink off and on. But no much. She will not eat. I was thankful vet didnt charge. I have been crying so much as she is pretty much my child . please any advice would help. Should i get a second opinion? Should i try feed her myself?
