The little one was sneezing from the rescue and she had her vaccinations yesterday the vet said she's fine. Since yesterday the older one is now sneezing three or four in a row and is having droplets with it. No cough or running nose. Eating and drinking well. I've been googling and keep seeing herpes coming up I'm worried sick. Is she allergic to the new one or has she just caught a cold? Can I do anything?
