This is an unusual situation. If Seraphiel goes outside and comes into contact with other cats, this could explain why she frequently acquires ear mite infections, but perhaps you are treating her quickly before the mites can be transmitted to your other cat. Even though Seraphiel was diagnosed with ear mites (I assume microscopically by her vet), there is a chance that she could have a concurrent bacterial or yeast ear infection, which is often caused by underlying allergies. If this is an ongoing issue, consider starting both cats on Revolution or Advantage Multi on a monthly basis to prevent fleas, ear mites, heartworm disease and some intestinal parasites.
