Allergies

I noticed last summer that my cat had a lot of congestion and he was sneezing a lot. When I took him in for his regular check up.. his vet said there isn't really anything they can do for that. I have noticed that he sometimes has trouble breathing (through his nose). So my question is.. Is there anything that I can do for him?

Find a new vet ... A steamy shower may help but you really need to find out if it is seasonal ??? enviornmental ??

I do need to find out.. so I think I will find a new vet. I know he is uncomfortable with his sneezing and congestion.
