I'm just wondering, if you're allergic to cats, do cat allergens harm your lungs as bad as second hand smoke?

No: The dander just causes a histamine reaction which is not damaging like second hand smoke.

Cat allergies: Cat allergies can give you asthma symptoms which usually reverse when you are not around cats anymore, unless you live with one. Smoking predisposes you to a myriad of lung issues, and can potentially cause lung cancer. If you live with a cat, get desensitized, see an allergist.
