I can't find it anywhere either...it's just not out there anymore. I've yet to find a reason why it's no longer available, but all the major catalog store (jeffers, valley, kv, foster/smith, etc) list it as backordered or out of stock. None of the other local farm and feed stores have it either.
Terramycin ophthalmic is just GONE.
I haven't found an alternate OTC ointment, either.. I've considered neosporin before, but if you read the label on neosporin is says specifically NOT to use it in eyes..
So...in the meantime...what we've been using is called "NFZ Puffer".. It contains an antibacterial agent called nitrofurazone, and it literally comes in a powder form that you "puff" (and by puff, I mean shoot a stream of powder) directly into the animal's opened eye. I know, right? ....
I'd imagine it's pretty rough at first, but it's highly soluble. As the animal produces tears -- a pretty natural reaction to having your eye pried open and shot full of powder, I reckon -- the tears dissolve the powder and distribute the antibacterial medication all around the eye.
You'll find it in the livestock section of TSC...because that's what most folks use it on...though it's actually labeled for dogs and cats...but not livestock...even though it's sorta designed to be practical in working livestock...and despite the fact that most folks probably can't even fathom the idea of shooting a stream of powder into their puppy's or kittie's eye..
I know...it makes no sense to me either..
But I'd imagine that if you didn't want to puff it straight in their eye, you could always mix a little powder with some distilled water and make some impromptu antibacterial eye drops.. Since it's labeled for use in cats' and dogs' eyes, should be safe enough..
Just a thought. Hope your kittie gets straightened up.
