Can cats be taught to  go potty on the toilet?
user
No, cats aren’t trained animals.  They can be taught some tricks like coming when called or jumping on a stand, but they’re not trained.

It doesn't sound like something a cat can do; but I heard that they are selling a book on Amazon about this.

You might want to check with Amazon to see if that book is legitimate.

I just don't want to waste my money if it doesn't work.
