I am very fortunate to have two adorable cats. However, upon moving into my new house, they decided to stop using their scratching post & start using my keyboard to sharpen their claws. This left me with something like this: my question is do i need to replace the entire keyboard? or can i just reattach the keys (including the little rubbery bits underneath. they took those off too in some instances) thanks! ps - told you they were cute!
