A known fact from our experiences is that toast always lands butter side down. We also know that cats always land on their feet. Let’s start taking advantage of this!

Is Your Cat Lost?
If you can not find your cat, you should really look everywhere, even in the closet:
New Invention For Exercising Your Cat:
If the only thing your cat does is sleeping around the house, you might consider this invention (issued US patent): EXERCISING A CAT A method for inducing cats to exercise consists of directing a beam of invisible light produced by a hand-held laser apparatus onto the floor or wall or other opaque surface in the vicinity of the cat, then moving the laser so as to cause the bright pattern of light to move in an irregular way fascinating to cats, and to any other animal with a chase instinct.

"The Cat Annoyer"
...or Three Mouse Monte for Maximum Feline Aggravation
The idea is something like a puppet show for cats. The fuzzy mice dart in an out of their "mouse holes", controlled by you. We guarantee that, once you leave the house, the cat will have that thing shredded into 8 zillion pieces by the time you get home. Source: here

Various Ways To Bath Your Cat:
Have you tried to bath your cat? You should do it equipped with this technique:

MOST EFFECTIVE METHOD OF BATHING A CAT 1. Thoroughly clean the toilet. 2. Add the required amount of shampoo to the toilet water, and have both lids lifted. 3. Obtain the cat and soothe him while you carry him towards the bathroom. 4. In one smooth movement, put the cat in the toilet and close both lids (you may need to stand on the lid so that he cannot escape). CAUTION: Do not get any part of your body too close to the edge, as his paws will be reaching out for any purchase they can find. 5. Flush the toilet three or four times. This provides a 'power wash and rinse' which I have found to be quite effective. 6. Have someone open the door to the outside and ensure that there are no people between the toilet and the outside door. 7. Stand behind the toilet as far as you can, and quickly lift both lids. 8. The now-clean cat will rocket out of the toilet, and run outside where he will dry himself. CraigList has a second method too.
