No I think she was referring to there sneezing sounds they do make! When something is new to them and they are smelling it for the first time you can hear it and when they are talking to eachother in the pouch! I thought Zoey had a cold the first couple times she did it and I rushed her to the vet and he said it was normal!
I wouldn't want to discourage anyone from taking there new babies to the vet I think a check up is always a good idea for all pets! And because your a new worried mom it may help to hear that your baby is healthy! It always makes me feel better when someone else tells me!
Signs to look for with sneezing is runny nose, watery or cloudy eyes! If she has any of those then she should go strait to the vet!
But once again a helth check is always a good Idea!
Lots of luck!
