Thanks for your replies guys.
twocatz,sorry to hear about your cat,what kind of treatment is he on,do you have to give him anti viral drops also and would you say he is in good form,eating/drinking etc.
Rfaulkner,hope everything works out for your little guy asap.
Sparky is getting Tobramycin and they gave her a NSAID drop for pain. I am not giving her the NSAID as I read it is to be avoided with a corneal ulcer, it slows healing. I can't get in to see my Vet until late tonight so I don't know what she'll want to do. Sparky's is not viral though, I think it is caused by a condition called entropian, the eyelashes turn in and scratch the eye. If that is the cause it will be surgical. Good luck, sounds like your Vet is covering the bases.
