Foxes are clever and tigers are cunning. So, what's your cat's safety school?

My cats have no safety school. The will climb anything. Their favorite precarious perch is on top of the narrow computer chair, while someone is in it. They enjoy playing with ant traps, chewing rubber bands, and dragging my husband’s dirty socks and underwear into their litter box when it has not been satisfactorily cleaned. They love to get on top of my table, on my laundry shelf, between my shower curtains while the shower is running, and into any cupboard or closet that is left open for a half of a second. They also like to hog my side of the bed until I am curled up so much onto the hubby's side that he is falling off of the bed. These habits that they have acquired in their less than 1 year of life, have led me to believe that there is no such safety school for cats, they learn by error and that is why they have 9 lives. I am sure they have lost 2 or 3 while being scared to death when my husband rants at them and chases them down with a squirt bottle yelling "Bad bad kitty gets the water", barreling at full speed head first into walls while playing fetch, falling off of the top shelves, and getting thrown off of my bed, table, and anywhere else they are not supposed to be.
