While we're on the subject of home remedies, allow me to share
the technique I learned elsewhere for keeping the toilets in my
house sparkling-clean. :-)

1. Put both lids of the toilet up and add 1/8 cup of pet shampoo
to the water in the bowl.

2. Pick up the cat and soothe him while you carry him towards
the bathroom.

3. In one smooth movement, put the cat in the toilet and close
both lids.  You may need to stand on the lid.

4. The cat will self agitate and make ample suds. Never mind the
noises that come from the toilet, the cat is actually enjoying
this.

5. Flush the toilet three or four times. This provides a
"power-wash" and rinse".

6. Have someone open the front door of your home. Be sure that
there are no people between the bathroom and the front door.

7. Stand behind the toilet as far as you can, and quickly lift
both lids.

8. The cat will rocket out of the toilet, streak through the
bathroom,and run outside where he will dry himself off.

9. Both the toilet and the cat will be sparkling clean.

Sincerely,

 The Dog
