Yes, I agree. Most URI's in people as well as in cats, are caused by viruses, and antibiotics are pretty much useless for this. They are only good for bacterial infections. And in fact, because the antibiotics are not specific for the one particular strain of bacteria that's causing illness, they kill off a whole lot of the beneficial bacteria in the gut, which upsets the balance of intestinal flora and can cause other nasty issues. Bottom line is - antibiotics used properly and for the right reasons are great, but should not be used every time there is a URI. But like sugarcatmom says, sometimes when a person is fighting off the initial infection, they may go on to develop a secondary bacterial infection, which can be treated with antibiotics. There, now that I got THAT off my chest, I feel much better!!!
