Toliet trained cats?

If you have a cat, you will understand the tediousness of cleaning the cat litter tray and how, if it is left too long, the smell can become rather unpleasant. Recently whilst researching different cat litter trays and cat litters online, I came across an article concerned with training your cat to use a human toilet! Now the idea of this sounded perfect……but the implementation of it is rather a little more difficult!
Even though the article explained the best way to get your cat to start using a human toilet I have to say my cat Ginger did not seem to grasp the idea!
It is quite a shame really as it would have been great not to have to spend money on buying cat litter and not having to worry about cleaning it regularly!
