Interesting, perhaps not such a ridiculous question after all.
Can't believe the mess of those 5's!!
Maybe if I got them a nice new scratch post and put it in the same room, playing with them around it, maybe even using some cat nip to entice them to it. Then if they went near the speakers I could spray them with water? Certainly for the first few weeks I wouldn't leave them alone with them until I'm sure they wouldn't touch them. I'm sure it's just an exercise of training them, but anyone with Siamese cats will know, despite the fact they're super intelligent (for a cat), they also don't like being told what to do. Reminds me of myself really!!
