This is a day in history when tornadoes ripped through Ohio, Pennylvania, New York and Ontario in 1985. I lived in Harmonsburg, Pennyslvania at the time and remember these tornados quite well. To me the scene looked like what you would expect from a nuclear war. There was nothing left in many places. Seventy-six people were killed after 41 tornadoes touched down in this outbreak.
Going back in history 250 thousand people were killed 526 AD when an earthquake struck Antioch, Turkey. In 1935 40 thousand were killed when a 7.7 magnitude earthquake occurred in Pakistan. Then again in 1970, 47 thousand were killed in Yungay, Peru when the Ancash earthquake caused a landslide that buried a town.
On of the most famous disasters on this day was the Johnstown Flood that killed over 2200 people when an earthen dam overflowed its top and sent a wall of water as high as 60 feet with the town of Johnstown, Pennsylvania in its path. This was the 1889 Johnstown Flood, there have been others in 1894, 1907, 1924, and 1977.
I have been putting a lot of tips on about dogs and cats. I am not sure how many people are reading them, but does anyone have any questions? The tip of the day is if you are not sure, ask. Don’t try something that is going to turn into a bad habit.

I just heard something new yesterday. When you cat does that “stepping” behavior on you, that is called “the milk dance” or “milking behavior”. This is what the cat would do to the mother to stimulate milk production. It is a sign of affection. I was thinking about that and what kinds of affection dogs show. Of course we know they like to lick us. but I was thinking about behavior that goes back to when they were puppies. Nipping is something the puppy would do to it’s litter mates to encourage them to play. When I was in college I took a philosophy class called Freedom Leisure and Play Activities. Animals play, just like we do, to prepare them for an adult life. With this in mind, it is natural for a dog to want to chase, catch, and mouth things. Encourage this play and become a part of it with your dog or cat. Just don’t play catch with cars and buses. I am talking about a ball or a Kong frisbee.
