I trained my cat to do its business in the toilet. I cannot tell you how much better this is than any other solution. There are training kits that our friends and family have now used for their cats.
If you live near the ocean, you won't want to do this if your cat could be a toxoplasmosis carrier (I.e. is outdoors or otherwise could be eating rodents). Apparently toxoplasmosis makes it through water treatment and harms sea mammals.

Otherwise, this is a great way to go.
