I recently rescued a litter of 6 kittens and after they went to the vets for their 2nd shots one of them developed a goopy eye and 2 of them started sneezing. Back to the vets we went and they gave everyone 7 days of antibiotics and eye sauve. After a week of this and I thought all was well the 2 that were sneezing are sneezing again. Anyone got any suggestions.
