haha, there is a product called the Litter Kwitter that I used to help teach my cat to use the toilet. He is actually on the product packaging because I sent a picture of him using it in.
The kinkajou only gets pissy with me when she is just waking up and I am trying to take her food bowl out to fill it up. Never really aggressive but she does yell at me.
I'm saving cash for one of those. There's a breeder near me that I visit. A year or two down the road, I think I'll have enough spare $ and research done to really go ahead and seriously consider it. I love them, though!
