Do you want to make a mouse happy?

Because nothing makes a mouse happier than a fruit loop.

You give a mouse a fruit loop?

Oh man, it's like watching a human eat a car tire.

Bethany Brookshire is an author and journalist.

And while plenty of people see mice as pests, she is a special place for them in her heart.

They eat it all in one sitting.

They end and they're like, measurably larger than when they began.

That's amazing.

We just flop off in the cage, just leap it off.

And wait, that's just a single fruit loop, right?

It's so cute, yep, yep.

Bethany doesn't know about the fruit loop thing because she keeps mice as pets.

She knows about this stuff because in a previous life, she used to work as a biomedical pharmacologist

studying treatments for things like chronic depression and ADHD.

And so I would give them their little injection and mostly injections are given in their little

bellies.

So you just pick them up in one hand and you tuck the tail with your pinky because otherwise,

they'll get it in the way.

And you just give them a little quick shot and then you put them back in and I would do this

at the beginning and at the end of every day.

And when I was doing experiments, it would depend on the experiment.
