Yes, it was a catastrophe.

Truth is, cats are great panic generators and as fuzzy beings themselves,
they're also great fuzzers. Only, normally they restrict themselves to
fuzzing clothes, computer fans, their owner's food, spreadsheets, the nose
of anyone alergic to catty fuzzy feelings in a 100m radius, word
processors, and IRS forms.

However, it is the first time I've seen documented proof that a cat
sucessfully fuzzed an input device into a panic. Must be a lolcat's revenge
to the lack of mouses since touchpads took over. And Linux has no
cat-proofing for the keyboard and touchpads[1], which will leave us
wide-open to surprise fuzzer attacks from the lolcats! Maybe we should
issue a CVE about it?

;-)

[1] Windows _has_ third-party cat-proofing for keyboards, by detecting
clustered pressing of nearby keys. I don't think it can yet figure out a
catpaw press on the touchpad, however.
