About a dozen years back, I posted with the subject line “I Can Haz Broken Glass”, because my then cat Smokey had rolled off the shelf, landed just so on the computer and knocked it end over end, cracking two slats in a favorite chair and breaking the computer screen.

Last night, my current cat Hamish--who is about twice Smokey's size--accomplished much the same thing. This time the computer fell at a different angle, so nothing broke except the plug for the USB hub. (It was not the only thing to come unplugged, but the only plug that physically broke.) The most time-consuming part, aside from dashing to Amazon to order a new hub (dirt cheap!), was looking for my reading glasses. Apparently frightened by the commotion, they had hidden under the computer table.

I was mildly impressed by the fact that when I plugged the computer in again and turned it on--fearing the worst--everything came right back up, and the YouTube video I had been watching resumed exactly where it left off.

Nice going, Hamish.

Cats, eh!
For some unknown reason they have a skill to knock things over.
Good to know resumption appeared to be close to seamless.

From this, I would conclude that the damage (D) is inversely proportional to the mass (m) of the cat. D = k/m

You have run this experiment twice now. Can we assume some order of magnitude estimate for the constant k?

Caution -- As sample size here is small (n = 2), it is quite possible that D is inversely proportional to m-squared or even m-cubed. So, more data is required. Please repeat this experiment with more (different) cats.

Given the current sample size, I think we’re looking at m-cubed. Hamish is 15 pounds and did $10 of damage, while Smokey was 8 or 9 pounds and did $40 or $50 (I forget) in damage.

On the other hand, I’m sure I have had rats (range .5 - 1.2 pounds) take the same tumble, doing no damage at all. So the formula may be more complex than we yet suspect.

Had a wolfshund, 160 pounds, with a very long heavy tail that liked to wag ... and wagged an open IBM laptop off a coffee table. Broke the hinge and smoked the screen. Out of warranty and non-repairable, of course. But for the fact Waffles was a lovable family member something dire might have ensued! Data was salvaged and parts were accumulated for a few laptops on hand, but the loss was probably $1600.

Do dogs fit into the equation under discussion?

Ouch. But unless the equation considers only the weight of Waffles' tail, anything involving the inverse of m^3 is not going to fit.

Hamish often steps on my macbook, but since it is barely ajar (listening to PBS Eons in bed), all he does is close it. Mysteriously it takes several seconds for the sound to stop.
