breathing

My 9 week old kitten has been making this noise like he's having trouble breathing. His nose sounds stuffy too. What could this be? Besides going to the vet is there anything I can do?

Sounds like he could have a URI, a vet visit will be needed for a full checkup.

Being so little l would definitely have a vet check

Kittens are prone to getting an upper respiratory infection, the kitty equivalent of a cold or the flu.  It can be very serious if it causes them to stop eating or drinking, which often happens.  The vet can't give you anything to treat the infection, which is a virus, but he CAN give you antibiotics that help with the secondary infections.
