How Much Exercise Does an Indoor Cat Get?: Week Six

I now understand why Snickers loves this toy so much and yet this love fails to translate into higher activity numbers: Laziness.


Speaking of laziness, I grew tired of having to track down the cat, remove her collar, un-tape the Fitbit Classic tracker, charge it for a few hours, and repeat the process in reverse every single week, all while losing (precious) data about the cat’s every step. Thankfully Fitbit now makes a perfect solution to my obscure problem: the Zip, a cheap, tiny, lightweight tracker with a battery that lasts six months.

The magenta Zip even matches Snickers’ collar. Note the blurry red wand at which she is staring.

  • The daily breakdown graphs are visibly different after the Zip tracker was activated (9:30 on Friday, 19 Jan). The Classic and Zip trackers are both designed to count the steps of humans, and cannot be expected to accurately measure the exact number of steps of a twelve-pound quadruped, so this difference between the two is understandable. The general patterns of activity are still apparent so the Zip still seems like an excellent means of measuring general cat physical activity.


  • Tuesday evening (6:30-9) was the final recharge break for the now-retired Classic tracker. No more recharging! Woo!


This has been -and continues to be- a tremendously fun silly little experiment. Recently I have been busy working on other frivolous software endeavors, and my time for cat-entertainment-engineering has been limited. I will probably not do another detailed analysis post for a while; at least until I have built something new and had the opportunity to test it on the cat. An iPad app is halfway complete, and I’d like to do something with lasers.

In the meantime, you can continue to watch Snickers’ progress -every day- on her Fitbit profile.

Cut-throat competition



  • The beginning, wherein I attach a Fitbit tracker to a cat
  • First week of data, when I learn interesting things about how my cat spends her time
  • Second week: introducing a new toy
  • Third week: automating that toy to (hopefully) provide the cat with more exercise
  • Fourth week: laughing hysterically at the resulting toy improvements and wondering if they are having an effect
  • Fifth week: looking at the results
