Well, shit, would you want to eat somewhere that had thin rats???
Or, given the lunatic fringe showing up on this board lately, what did the size of the rat have to do with anything? Would you have said that there was a ni**er rat crawling along? I didn’t think so. Take your sizism somewhere else. I recognize prejudice everywhere I look (if I look hard enough) and I’m not going to take it here. 
Whether this is sarcastic or not, I think it’s funny!
“Chinese restraunts: Curbing the local cat overpopulation problem since 1910.”
Relax. Its just a joke. 
Fagjunk Theology: Not just for sodomite propagandists anymore.
This could be something of a localized urban legend, but it’s not about chinese restaurants, so it might deflect some of the vitriole.
There is a chain of restaurants here called Food Star. Worst name ever, I know. There used to be three of them. Now there are two. One was closed down because a random inspection revealed that most of the meat they were serving to the customers was actually cat. The freezer was packed to the gills with cat-meat.
YUMMO!
Blame gatopescado if you don’t like my little story. His quip reminded me of it 
I sliced my middle finger once on a tomato slicer. Ouch!! Immediately, I stopped, and put the slicer in the sink to be washed and disenfected by someone else. Meanwhile I went straight to the hospital. I could only return when the stiches came off after a month.
My advice? Go to a place with an open cooking area (i.e., you can see what they are doing) and check the report card on their last health inspection.
And, it is true that some parts of China do not have the same standard of cleanlines as the US.
I must be strange, because stories like this never turn me off a particular food. In fact, some Chinese food would taste really good right now.
Of course, I usually just get take out from the local Giant Eagle.
There’s a chinese place near where I work. Good food - most of the time. It depended on how recently immigration had busted the joint. If it had been a while, the food was pretty good. If they’d just recently been busted, they’d have a new batch of illegals in the kitchen who weren’t quite up to speed, and things wouldn’t be quite so tasty.
Then there was the place with the mouse crawling around the floor …
