My cat is addicted to a laser. They don't cost much and you can sit in your easy chair and give kitty one hell of a workout with the flick of your wrist.
I find that if my cat gets a good workout he is less likely to be destructive or annoying. Especially a house cat who does not get to express his natural instincts outside by climbing trees, sharpening his claws and stalking butterflies. Around here if I turned my cat loose something dire would happen to him so it is up to me to stimulate his life with play. I am pretty lazy sometimes and the laser provides him with what he needs and I get to relax and laugh.
Oh and by the way, get a good laser. I bought one at the dollar store and the switch on it stopped working within the hour.(Kitty was very frustrated) Expect to pay around $5.00 for a good one. Don't waste your time and money with the cheap ones.
