Many pets may have some strange or bizarre behaviour and sometimes we can not find a perfect explanation for that.
For example, dogs use to smell the other dog's butts (and other parts that I’ll not mention here, but you guys know on what I am talking about it…)
But, anyway the The Summoner of Leviathan might be right if she had a previous owner who abused her or something, or Judge Judy, saying that she's obviously a sado-maso-type cat... beyond than that I can really say. But it’s very weird because cats don’t like those things…
And Leeza... don't get mad... :D
