I'd have scooped them up!! That's disgusting. I had that happen one time at a pet store in CT. I was so loud, commenting about how they looked sick, sneezing and ookey eyes, all the customers in the store gathered around the bin they were in. I made it known that I was pissed and they should get them to a vet ASAP. Don't know what the outcome was. I can only HOPE that they got the medical attention they needed!
