“…Important diagnostic possibilities for muscle tremors and fasciculations in cats include intoxications (organophosphates, carbamates, organochlorines, strychnine, pyrethrins and pyrethroids, mycotoxins), metabolic derangements (hypoglycaemia, hypocalcaemia, hypokalaemia, hepatic encephalopathy, uraemia), encephalomyelitis, feline hyperaesthesia syndrome and degenerative and inherited cerebellar diseases. 3 , 4 This case report presents a novel clinical presentation of a feline GI obstruction in which the initial clinical signs were severe muscle tremors and fasciculations reminiscent of permethrin intoxication but demonstrated subsequently to be related to hypochloraemic metabolic alkalosis due to complete proximal intestinal obstruction.…”
