Cat trouble

I got a cat last year, rescued from a laboratory, who is finally trusting and loving me and now I have to catch him for a week, twice a day to put ointment in his infected eye. JOY!!!
So I got to single handled (note to self: need to get boyfriend for a week *g*) catch a cat that doesn't like to be held open up the tube and ONLY put the ointment in his eye.
Somehow I don't think this is going to end up very well...

If I don't post for a while that might be because the bandages prevent me from typing ;)
I do love him but cat's are damn scary when enraged!
Sharp teeth, four paws with claws and why oh why did I just buy that scratching device for him to sharpen his nails...
