When I put my Mac Pro asleep after an hour or so it wakes itself up. It just suddenly comes on.

Any suggestions?

USB devices attached?

Cat in the house?
I have plenty of more important things to do, if only I could bring myself to do them....

Try disabling "wake for network activity" in the Energy saver control panel. Some network systems broadcast wake signals every now and then to make sure that all of their equipment (cable modems etc) are awake to receive updates.
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.
