Back in 2004 when I was still working for a housebat rental company at the south end of the lake an interesting thing happened as I was working at the houseboat return dock. I noticed a 54' houseboat screaming toward the dock way to fast and motioned to the driver to slow down as he expertly reversed the engines and softly bumped the dock as I tied the ropes to the cleats. He obviously was in a hurry so I asked him if there was anything I could do to assist him. No he answered, he was in a hurry to get to the Page hospital where his wife had been life-flighted from the back of Last Chance canyon. When I asked what happened he told me a Bobcat had entered his houseboat through the back door which had been left open. Apparently the cat had walked along the catwalk on the side of the vessel, came inside the rear suite and attacked his wife. They repeatedly screamed at the cat but it kept attacking her. The man frantically looked for something to hit the animal with and found the shovel on the front deck which he used to defend his wife. The Bobcat would not give up attacking and eventually the man killed it with the shovel. N.P.S. responded to the mayday call and flew her out to Page then to another hospital where I heard she recovered. The cat was examined and did not have rabies. There had been a sighting of a bobcat a few days earlier in Last Chance stalking a 10 year old boy. This was probably the same animal. After seeing and hearing about injuries, snakes and critters a person will be a little more cautious when on the lake.
