Feline conjunctivitis is a doxycyline deficiency!
If you have been to any of our CE sessions you may have heard the mantra “feline conjunctivitis is a doxycycline deficiency”. But surely no feline ever expired through lack of doxycycline! So do we mean? The two most common causes of infectious feline conjunctivitis are feline herpes virus (FHV) and Chlamydophila felis.

FHV is of course a virus and won’t respond to doxycyline but coinfections are common. Other less common causes are Mycoplasma felis, which will respond to doxycycline, and rarely calicivirus which is usually self-limiting.
