Not until recently, unfortunately.
Phinehas is on lysine, Tobramycin (eye drops) and another eye drop I can't remember the name of right now for feline herpes virus which I found out is apparently a common respiratory pathogen in cats. In fact, most cats have this, but their immune systems keep it at bay.

Malachi is also on lysine (amino acid), Idoxuridine (eye drops), Tobramycin (eye drops) or Gentamycin (eye gel) and the same eye drops I can't remember the name of along with Acyclovir (oral anti-viral medication) for the same thing Phinehas has, only he has a more serious case which is why the poor thing is on more meds.

I'm hoping they will improve and get over this hurdle so I can stop the medication. It's likely they could have flare-ups from time-to-time in the future, so the eye drops and lysine will probably be my long term treatment.
