4 weeks ago I found a kitten on the street. Approximately 4 months old and it was sick and hungry. I took it to my vet and had him treat it. Once I decided that I wanted to keep the kitten he started treating the kitten more aggressively. It was an upper respiratory infection. Probably FCV. Hes been on antibiotics for 4 weeks. B Complex, Non steroid, Ventolin, and a decongestant. His appetite is fantastic. Bowel movements are normal. Coat has become shiny. He is alert and plays. Sounds healthy. Looks healthy. But his blood tests( 4 over the last 4 weeks) show and increasing WBC and a lowering of LYM. (WBC 41 today and LMY% 7.8) My vet read about the antibiotic that my cat is taking causing high WBC even if the cat has improved. Like a false positive. I had read the same thing myself and I cant find it again on the internet and dont know the name of the antibiotic off hand. The vet immediately took my kitten off that antibiotic and put him back on the first one he had been on. He said he will repeat the blood test tomorrow. I'm looking for ideas. The cat seems absolutely fine ...but those blood tests...
