_increased thirst balanced with increased urinating
_drew 300ml abdomen fliud which was cloudier and pink/yellow colour
-had 2nd vet make 1M auto-nosode from fluid
_no instruction so gave cat 1 dose 3xday, then 2xday for past four days
_need advice on frequency of dosage???
_do I stop nosode or change to LM or some other potency???
