Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I only recommend erythromycin or terramycin be used in a cats eye. I recommend, if Riley is having an issue with her eyes, that you see a Veterinarian before putting anything in them. You don't want to do more harm than good. Cats are very sensitive and can react to many eye medications and can react to them all! I hope this helps and I wish you the best!

Any ophthalmic medication will be more expensive than other meds. Ask your veterinarian to write a prescription for your kitten's needs. You can then take this and shop for more affordable pricing either online or at other pharmacies.

Hello, thank you for using Pet Coach. So sorry that Sid is having this issue. Chloramphenicol does come in a drop - we can get it here in the U.S. Maybe it is not available in the UK? I am unsure about this. The ointment is likely a better choice in this instance anyway as it lasts longer in the eye so you can apply it less frequently. If you get a drop you will need to put it in quite frequently (like every 2-4 hours) as it doesn't last long. As for the ointment just sitting on the eye, that is likely OK. Enough is probably getting where it needs to be. If he is having trouble blinking you may have to do it for him. I usually apply the ointment and then close the eyelids with my fingers and gently rub the upper eyelid to spread the ointment over the eyeball. I do this whether or not a tarrsorrhaphy (third eyelid flap) has been performed or not. I know this is not fun to do and cats are not usually the best patients. Just do the best you can. If he is trying to fight you, you may want to wrap him up in a heavy towel like a burrito with only his head sticking out. That may make it easier for you to medicate him. Hope this helps. If you have more questions please feel free to post again. Best wishes!

Hello, Yes, this drug can be prescribed to be given orally to cats for the treatment of herpes. I'd recommend making an appointment with your veterinarian to discuss the best treatment plan for her. Special pharmacies can make oral medications in cat-friendly flavors, like tuna, and this can help make the medication experience much easier. Sometimes this disease is still going to require eye drops as well though. I'd recommend trying to train her and make the eye drop experience better with positive reinforcement, treats, toys, etc to maintain this condition best over time. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about your kitty. I'm assuming the vet who prescribed these did a corneal eye stain to make sure the surface of the eyes were not damaged. You can place the drops in the eyes as directed and then wait about 15 minutes and follow with the ointment. Great question.
