Does anyone have ideas for indoor door locks?

[Arbiesmom]

I'm getting sick of my house looking like fort knox! Everywhere is either padlocked or tied up with string on hooks. I know you can get the bathroom door type locks but I don't really want them all round the house but if they are the only means of keeping Arbie out I will have to resort to that!. He has taken to going into my music room - (it would be funny if I could trust him not to eat anything in there) and trying to "play" my keyboard He puts his paws on it then gets in a frenzy cause it's not switched on and he starts sniffing around trying to find why it's not working. That's ok when I'm there with him but he keeps wanting to get in on his own and I can't trust him by his self.

How about those child-proof covers that go over the doorknobs that take adult sized hands to turn? I'm not sure if I'm making this clear...does anybody else know what they're called?
