Wheezing can be a symptom of anything from a hairball to an upper respiratory infection to bronchitus to cardiomyopathy to Aluetians Disease. All are treatable, most are curable and a vet visit shouldn't be delayed. In the meantime, you can give a hair ball laxative. It can't hurt, and if it is a hairball, can only help. Best wishes!
