Coton de Tulears are small, white, cute, stuffed-animal like dogs. They are very hard to find because they originate from Madagascar. They are hypoallergenic and non-shedding.
When something is so extremely cute, so absolutely adorable that you just can't stand it, you have reached your Cuteness Quota, and can't take any more.
While looking at a video of baby animals frolicking with human babies, I became so overcome by my Cuteness Quota, that I just passed out.
