First you pop, then you stop
Our pet rabbit used to have an annoying habit of chewing on his plastic litter bins, but mercifully, he stopped doing it. Until, in about the last two months, he's picked it up again. It seems to have started after one night when we left him inside his hutch, without space to run around, because we'd wanted to keep the floor clean for the company visiting. Maybe he started chewing it out of boredom and discovered he liked it again (rabbits love few things more than chewing), but, gah. It's mildly annoying to me, but it couldn't be a more agonizing sound to 
bunny_hugger and so he can ruin her night with just a little nibbling.
I don't know how to get him off chewing the bin without setting up an unwanted association, like, ``chew on this, they come over and deliver food''.
Meanwhile a bunch of posts have gathered on my mathematics blog since the last roundup here. If you've missed them, please consider:
- Reading the Comics, January 29, 2015: Returned Motifs Edition, or where the last roundup left off.
- How My Mathematics Blog Was Read, For January 2015, a review of the readership numbers and a list of countries, which people like seeing.
- Denominated Mischief, drawing an example from Magnificent Mistakes in Mathematics in which you can prove that 7 equals 11, if you aren't careful.
- Reading the Comics, February 4, 2015: Neutral Edition, so called because I got to touch about trying to treat mathematics as culturally neutral.
- The Thermodynamics of Life, a reblogged piece about working out just how bodies work.
- At The Pinball Tables, because the draw for machines at last league night spawned a couple nice little mathematics problems.
- How To Count Fish, potentially a useful way in which you might estimate a population too big to just count all up at once.
- Reading the Comics, February 14, 2015: Valentine’s Eve Edition, which was a holiday tie-in I couldn't make anything of. But there's dinosaurs talking about infinities, so you can enjoy that, surely.
And, if you want, you can get entries as they are made from the blog, or from its RSS feed, or you can add it as a Livejournal friend and read it on your own page, as you like.
Trivia: Among the reasons the American National Standards Institute adopted a seven-bit ASCII code in 1963 was that punched paper tape, still in common use, might be too weakened if eight holes were punched across it.
