Rats are rather clever little creatures. I have potty-trained my two male rats within a single week.
Until recently, they have found a new favorite spot.
The method I used to teach them was association of smell. Simply move their litter to the litter-box in the corner, and soon they picked up on it.
The problem is, they now started urinating in the other corner. I assume this was due to one of the two accidentally doing so, and the other then assumed by association of smell that this is an OK place to do so.
How do I teach them not to do that anymore? I tried cleaning it profusely, but it doesn't help all that much. And I am not really sure how I can move urine, or the smell of it, to the litter box..
