One word of caution about laser toys.
They are really great but some cats can get really frustrated with them.
I played with cat once with a laser toy and the poor thing went crazy for a while.
He couldn't understand why he couldn't catch it and wouldn't settle after stopping play. He ended up panting heavily and constantly searching for it.
I read some research about this and it reccomends finishing play with a different toy that the cat can actually catch. This gives the cat a final "payoff" that is tangible.
I don't wish to stop people playing with laser toys as my ragdolls love it. Just to share what happened to me. I now always end laser play with a real catchable toy as I don't want my ragdolls going mad.
