I've been a cat owner for most of my life and if you know anything about having inside cats is that all cats would prefer to be outside if they could.  I found a site that specializes in invisible fencing for dogs, but they also provide invisible cat fencing. as well.

I can't imagine my cat getting a "correction" (fancy word for shock) because he crossed the line in the yard.  I've never met anyone that actually has used this product and I've been looking for online reviews.  It just seems a little crazy to me.

Here's a picture of the device:

I'm not saying that this is completely crazy because I'd love to see my cat, Kaspurr, stay the hell of of the kitchen counter.  Every morning he's up there in the sink licking the last bit of milk out of min or my wife's cereal bowl.  If I can find some really positive reviews I think I might look into this as a solution to keep my cat where's he's suppose to be.
 
 

I was wondering today how many cat blogs are out there and of those how many people actually read them?

You'd think that there would be quite a few, and in the same breath, not that many readers.  Few things in life are as subject as a relationship with your cat.

After further review, it's arguable that any or most relationships are subjective.  The reason I say that is that no one really cares about the dynamics of any relationship they're not in.  Unless it's soap opera or realty show quality.  What I mean is that no one is actively going to listen to you talk about your Cat.

It's like the Demetri Martin graph that indicates the ratio of cat conversation vs how "cute" you think the girl is.  Speaking of Demetri Martin Here's a Video on Him and relationships
