Angry Cat Site Block

A free, easy to use site blocker, that will show you an angry cat, telling you to get back to work, whenever you are blocked.

Completely free, no paid features.

Can block any words, websites etc. from the url.
This includes things such as "google", "google.com", "www.google.com" etc.
Any word that matches the url, will result in a block, which means that even single letters such as "e" will also work, even though I would not recommend to do so.
