I think this is the first time I've been able to refer to him without getting upset!
Adding for my information later: it was the brown fur eye his left.
- You can quote me
I **think** the only thing you really need to worry about with a soft grassy piece is a tiny bit of it getting lodged under the eyelid or to one side of, or behind, the eyeball. Otherwise, in the majority of cases what you've done, and what's been suggested, will do the job.
If it were me and it didn't clear up completely in a day or two, I'd make a vet appointment to check for any wayward pieces that might have gotten someplace they really shouldn't have.
It's a human thing of course, but I'm still freaked out that hey had hay IN his eye. Eeeeps right? If he would stop sleeping in the hay pile this wouldn't happen. I see that as a human sleeping in the pantry with a hand in a bag of potato chips. Lazy pigs.
