Guards sound like a good idea to me. I had a few dizzy spells last week from a new medication. This has never happenned to me before and has gone away now. As I get older this type of thing could get worse and guards could turn out to be cheap insurance. I will probably make some sturdy guards that can be lifted off easily at some point in the future. My cay seems smart on many levels but he is the one that caused the saying "curiosity killed the cat". He investigates everything very close up and thoroughly and got trapped inside a swamp cooler last year because he stood on top of the squirrel cage blower and it rolled him down inside. He was like a hamster on a exercise wheel when he tried to climb back out. He couldn't run fast enough to get back over the top, maybe because there wasn't enough room for his legs to get a full stroke. Just luck that I found him and got him out. I wouldn't have thought of that cooler as a hazard until then

. It's been stored there for a few years and now I've turned it so the blower opening is against the wall. Odd things happen sometimes! I will try to keep him out of the generator shed just to be safer but I don't think you can worry about every potential hazard in life. Everybody has to decide what level of risk to live with and the universe seemed pretty forgiving--- until Fukashima
