Not Ear Mites

I TOOK MY CAT TO THE VET AND SHE DID NOT HAVE EAR MITES. SHE HAS SOME THING I CAN'T REMEMBER THE WHOLE NAME OF. IDIOPATHIC.................. ANYWAY IT IS KIND OF LIKE A STROKE. THEY DON'T REALLY CALL IT A STROKE THOUGH BECAUSE THEY RECOVER COMPLETLY WITH IT. IT HAPPEN IN OLDER ANIMALS AND THEY DO NOT KNOW WHY. IT LAST FOR 2-3 WEEKS BUT SHE SOULD BE FINE. THE ONLY THING TO DO FOR HER I BABY HER MAKE SURE SHE EATS AND DRINKS BRING FOOD AND WATER TOO HER AND A LITTER PAN IF SHE CAN'T GET TO IT AND GIVE HER DRAMAMINE FOR HER DIZZINESS. THANKS ALOT.
