We adopted a 5/6 week old little boy six days ago! He's very active, popcorns, he eats and eats all day, his poos look perfect, his fur is shiny/smooth/dandruff free---but he sneezes fairly often. The day we brought him home he had a small bit of white eye sand/eye booger in one eye, but not any since and his eyes look clear and normal now. I'm guessing it was only some grooming discharge that didn't get wiped away? The first day he sneezed around ten times, and about five times the next morning. The last four days he's only sneezed about three times every day. We're watching him really close, and he seems perfectly normal other than that. No nose boogers. When he does sneeze it's usually after or while he's eating; whether it's hay, pellets, or a veggie. Could he have an URI without any other symptoms like this?
