My 7 month old norwegian forest cat has been sneezing a lot. He, however, seems to be fine. His eyes and nose aren't runny and he eats. He has a sort of congested-sounding, gargly meow and purr, but i've heard that the species generally has a trill as a meow anyway. Should i be concerned? Also... while i'm here, if he's been scratching his neck a lot lately, what kind of flea products should i use (assuming he has them- i have yet to check). Thank you for you time!
