Yes, most (if not all) can be trained to pee in a spot, but it does take time and patients in some cases. If you do a search for litter training on the forum's search you'll come up with several threads on the topic as well as tips and how to steps. Keep in mind though that although some chin's take to it right away others it can take weeks to months to figure it out, and accidents still do happen. Most chin's pick a corner to pee in on their own so that makes it easier, if you have a chin that does that. My boys literally just take a couple steps from where ever they are and pee :banghead:. I gave up after a couple weeks, I use fleece liners and it's not that big of a deal to wash, they at least only pee in their cage.
