My son took two cats from a Rescue Centre - one of which had Feline Herpes - was treated - but eye still weeps constantly. He bathes it several times a day with sterile saline.
We read on the internet of the following medications and wondered whether they were only available in USA or whether any could be sourced here:

1) Lysine

2) Herplex drops

3) Viroptic drops

4) Vira -A

Would anyone have knowledge of any of the above or indeed of any eye medication for this condition which can be sourced in UK.

Thank you in anticipation of help.
