First cat toys
Paper or a ping pong ball - Believe it or not, your kitty can have hours of fun with this. Simply take a large piece of paper, crumple it into a ball and throw it.
String toys - Attach a feather to a piece of string or use a fishing pole with fun creative lures at the end, such as bells or lights. Or take a child's sock filled with more socks with holes that you might throw away. Add catnip and you have a throw toy like those mice you buy in the store; you can even draw a face and whiskers and tie yarn on for tail.
Bag toys - Never use a plastic bag for these homemade cat toys, but instead use a large paper bag from a supermarket or department store. You can also do this with a cardboard box, just be sure to remove all staples and tape.
Box toy - Take a box, not to big, but that your cat can sleep in, put it on it's side make 2 holes on top and put one end of some string through one hole and other through the other hole and add a feather to one and a bell or something to the other.
Any old stuff toys, no buttons or pull off eyes on them please.
How about a knotted rope?
Take an old shirt you might trow away and draw a bone about a foot long, cut it out and then trace to make another. Sew the two pieces together and fill with socks or pieces of the shirt.
Socks?!?!?! Did I hear socks?!?! Stuff socks inside another sock and put a knot in the end.
How about tennis balls or find good strong sticks for fetch.
