Im gonna start him on gastric ulcer meds (zantac?) next week. I cant get him under a GA until he is stabilised.
Im quite convinced its not Cocciddia, it just dosnt seem to fit. I asked the vets about getting him onto Trimethoprim as I have some of that here but they dont feel thats the answer especially as wiping out his current cociddia imunity could leave him even more prone to it due to his low 'good gut' flora.
The most likely causes at the minute are a gastric ulcer or IBS.
