I don't see any evidence of injury or redness nor does she seem irritated by this.  She is fastidious about her grooming so this weepy eye is unusual.

Are polysporin eye drops effective and/or safe to use on a cat?

I'm looking for an easy remedy I can do at home in order to avoid a possible vet bill.  Of course I will take my cat in if the eye gets worse.

 

It is ok to use polysporin on cats (body cream and eye drops). 

If it is not better in 1 week, then it is best to goto your veterinarian. 

I suppose I could have googled this myself! 

I hope to hear from someone here who has used polysporin drops on their cat with successful results.

I imagine if I do this I will only get one chance to administer the drops because once she catches on there will be no way! 

from a vet site online- they use a lot of the same meds for humans on pets. ( I've used them before (upon a vet's recommendation) when one of my cats had a gunky eye.)
I'd never recommend using anything on a pet unless it was safe! You can do this- one wraps agitated cat in a blanket and kitty lock them between your legs so it has no where to go. 
Putting the drops in one time is not going to do anything. They need to be administered at least 2 x a day for a week to kill off the infection.
Or call your pet store and see if they carry this over the counter antibiotic. (it works the same- just having ;for pets' on the label ups the cost many times.
If you don't want to try the polysporin. If in doubt a quick call to a new vet (tell them you have a feral cat with an eye infection and if you'd harm the cat by using what you have in your medicine chest. 
Your cat isn't feeling well so go ahead and get this started.

so, okay!  I will get this done!  (she bravely wraps her kitty in a towel and kitty locks her between her knees) Drops administered and kitty treats given.  My cat it smart.  She knows she'll get a few drops of evaporated milk every morning when we have our coffee and 6 kitty treats when we have our wine in the evening.  She's a fast learner.  Perhaps she'll associate treats with eye drops???

Thanks g_sl!
