AR Cat & Some Bottles
My cat Smokey and my new AR. And that box he's sitting on is a great cheap cat toy. Just take a box and cut some various size holes in it. Then if you've got a cat that likes to chase fake mice toys toss it in the box and the cat will try and get through the holes in order to get the mouse. Either that or if you've got two cats one will get in the box and the other will swat it through the holes.
Here's a few old bottles I've got. I'm not sure what was originally in the green bottle but I'm pretty sure the one in the middle is an old Michelob bottle.
