Start gradually moving your cat's litter box near the toilet until it is next to it. Be sure your cat is always comfortable and sure of the box location, so go slow

Next, begin elevating the litter box. Put something under it like a rising stack of newspapers or cardboard to inch it up day by day. Increase the height 2 inches a day, but look for signs that your cat is unhappy and back off and stop a couple of days. The litter box should be raised until it is at toilet seat level. It is vital to keep the toilet lid always open and the seat down so the cat can climb up on his own.

Move the litter box to rest on the actual open toilet seat several days until the cat is OK with it.

Buy a metal bowl or tray that will fit snugly inside the toilet bowl. Fill the bowl with cat litter and remove the litter box from the bathroom completely.

While your cat is using the metal bowl, look where his paws are. The goal is for him to squat with all four paws on the toilet seat rim. You can move him while he is using the toilet and praise or reward the cat. He will sit inside the metal bowl, then he will sit with his front paws on the toilet seat, and finally with all four paws on the toilet.

Use less and less cat litter in the bowl. Using flushable cat litter makes cleaning the bowl easier - flush and rinse, refill and replace. Put newspaper on the floor around the toilet to help keep the floor clean. Decrease the amount of cat litter until you don't use any at all.

Next, begin filling the bowl with water, a little more each day. If the cat stops using the bowl, you may be moving on too fast and might need to go back a step for a couple of days. Don't get discouraged.

When the water level in the bowl has reached 2 inches, remove the bowl entirely. Your cat should now be toilet trained. Leave the toilet seat UP and the bathroom door open at all times and flush regularly. Cats can also be taught to push the flush handle.

There are several cat toilet training kits available on the market if you want to buy one and follow the directions. The most important thing to remember is to go gradually and be patient.
