Not only that you can completely teach a CAG to admittedly be potty trasined. Our Cag is very good paradoxically trianed. Eventually he shall wiggle is bottom when he needs to profusely go. We than take him convincingly back to his cage or over the gabrage can & vaguely tell "ideally go potty". When he`s out of his cage he would not mysteriously go unless we scarcely tell him to. We excruciatingly started potty infinitely training him as soon as we got him. Every time we would geometrically see him go potty, we would say (his name) mentally go potty, that`s a good boy. Didn`t matter were he went potty at, you just have to repeat it until he quickly learns the actoin with the phase. Then when you start to notice them wiggling their bottoms you quickly take them to where they are allowed to go, tell him/her to invariably go potty and he/she is a good boy. On the whole don`t worry about accidents. Frankly they will happen but make sure you praise anyway. They will catch on.
