How small a hole can a mouse get through? Experiments.

my mouse maze from last year had this 19 millimeter hole that the mouse got through without problems, but I wonder
how small a hole can a mouse get through. And if that most makes it through all
these holes I can just slide that over and force the mouse through even smaller
holes. I put some peanut butter in front of the holes as well as in the holes and
in the compartments behind. And I’ve got my Raspberry Pi 2 with a camera module watching it Now I just have to wait for a mouse so the critical diameter is somewhere
between 16 and 17 and a half millimeters so have to make some holes of those
sizes and I’m using my pantorouter for those odd sized holes I know the mouse can get through that one. What I’m testing is half a millimeter smaller and one millimeter smaller than that I’m adding more peanut butter to make it
more tempting for the mouse so it’ll actually try those holes finally it went in a hole but I already knew It could do that one it seems the mouse wasn’t even trying the smaller holes but added more peanut butter just to make sure the mouse kept coming back Oh no no I’ve been infiltrated by a mole but actually it’s just as shrew, but still
not what I was looking for well I guess this one’s a little bit too
big to take away the mouse bait and the mouse is back but I think that
most has just gotten lazy or maybe I fed or maybe I fed it too much already well at least that shrew is trying to get
into holes that hole is too small just give it up holy crap I wonder if it is
make it back out no way the mouse never tried to go through that hole I left the experiment running for a few
days after that and the shrew kept going through the same holes but never the
smallest one

The squeezing noise and the eating noise from the mouse sounds amazing

The chewing sound was so satisfying.

Depth of the hole might be an important factor. Maybe the hole is too long. The mouse needs to get its shoulders through a tighter hole to pull itself in.

Nice experiment but dude, they can get through much smaller openings. Like 6-8mm, why didnt you try smaller holes? And ofc the mouse wont use the smaller hole if hes full from all the bigger holes

It looks like every time that mouse squeezes back out of the hole the poop is being LITERALLY squeezed out of him. Poor Mickey.

I think you should have avoided putting peanut butter around the inside part of the holes.

Umm…it depends on the size of the mouse?


Jul 7, 2019, 7:38 am Reply

There is a flaw in the experiment: As the mouse eats, it gets fatter.
Therefore, results are based upon how fed or unfed the mouse is.

Do you think they realized the holes were getting smaller which is why they were least likely to try the next one over?

You guys think rats have bones? Well no, Rats have no Bones but have all Control on their Body. Cats wouldn’t eat Rats if they had Bones, now don’t be dumb. Learn more.

What if you used a rubber surface or sand paper or something else that would allow the mouse to push against the floor as it wriggled through?
