Please help! Very young kitten's eye is completely swollen shut.

[geoffh4]

My wife and I are fostering a litter of 4 kittens. They all had minor respiratory infections, except for one who is really sick. They are about 5-6 weeks old.

The left eye on the sick one is completely 100% swollen shut. When I try to clean it with a cloth, I can't even get it to open.

I took him to the vet last Wednesday and he perscribed amoxicillin and an eye drop called tobramycin. Ive been giving him the medication and eye drops twice per day (starting wednesday morning) and have yet to see much improvement at all. In fact, his eye is swollen shut so much at the moment that I dont even know if the eye drops are actually getting in anymore or doing anything useful.

What should I do? The vet said there wasn't any surefire methods, just TLC and dilligence with the meds, but I was hoping for some change by now. I know its only been 2.5 days, but still, I didnt expect things to get worse really.

Should I try to take him back to the vet? What more could they really do?
Should I forcibly open his eye to put the drops in?
Should I contineu to wait?

If things get better will he ever have a normal eye?

Im looking for some advice!!
