I am sorry to hear Fred is poorly. I agree it sounds neurological, but you
say it varies which foot and has come on so suddenly. The first thing that
comes to my mind is a potassium defect and that needs a prompt and urgent
blood test. Difficulty walking and neurological signs can be a potassium
problem and lasix depletes potassium. Cats on lasix often need a supplement
Its a dramatic thing, comes on quickly and is easily fixed if it is. I hope
this is all it is, it just sounds so possible with his symptoms.
