Silvie had a sore eye recently too (a wee infection, conjunctivitis or something probably, antibiotic ointment for 10 days sorted it out no probs) and I was in the vet with her a few times for that and for her regular arthritis check, and a blood test cos she's on Metacam all the time, and I'd been in with the guinea pigs to get their nails trimmed!
The vet asked me if I'd got a season ticket...
Don't care what they think of me though - rather see the vet and for them to tell me there's nothing wrong so that I know, than me worrying or the animals suffering!
