There are lots of ways to soothe dry lips without lip balm. Consider covering lips with a scarf when outside or running a humidifier indoors to stave off the dry air. Dehydration can cause dry lips so drinking water is another safe bet.One reflex to avoid: lip-licking.

Both were indoor-only cats that had no exposure to infected cattle or birds and didn’t consume raw milk.

One cat that died belonged to a worker on a dairy farm in a county known to have bird flu-infected cattle. The worker reported symptoms of illness before the cat got sick. That cat fell ill, tested positive for H5N1 and had to be euthanized. A second cat in that household also got sick, but it recovered. A third cat in the household didn’t get sick and tested negative.Meanwhile, an adolescent in the household got sick but tested negative for flu.
