How small a gap can a mouse get through?
 
As per the header.

I found a dead mouse today in a CU and the only entry point I could find was
where the tails entered and even that seemed too small to let the head
through.

You'll be suprised where a mouse can get. :-)

At a guess, a 2p piece sized round hole.

Less than that!, around 10mm or whatever that is in Mickey mouse
measurement!.....

The official government line is anywhere you can get a standard pencil
in. I didn't believe it till I saw it with my own eyes - a normal sized
adult mouse leaping up and vanishing through an air brick that I
couldn't even get my index finger into. It astonished me at the time.

From personal experience:

They can get through a 1/2" square hole (into an airing cupboard)
without any difficulty. I saw one do this when I surprised the little
bugger one evening.

They can also get through a 20mm knockout even when there are four
2.5mm singles running through it - Have you ever tried removing
carbonised mouse from a three phase isolator?

I'd guess any hole large enough for a woman's little finger.

That's a good guide but it doesn't have to be a round hole. A mouse's skull
is slightly flattened, broader than it's high. A round pencil hole wouldn't
allow a mouse through but squash it a bit and it would. IYKWIM.

Pencils are standardised? B****y EU. Is that a round or hexagonal pencil?

The only hole the mouse could have got into this CU was through a
rectangular with two very tight 25mm tails passing through. I do believe a
hexagonal pencil will fit.

How small a gap can a mouse get through ? well, measure the hole
where the tails enter the CU and that's about right for ingress.
however, there seems to have been some malfunction of the
mouses egress strategy :-)

apparently they temporarily dislocate their jaw to enable them to get
through tight holes.

Many rodents can get through a hole which their skulls will go through.
Its probably the only way they can measure it (lacking small rulers
and callipers).

Thats about right. Our mouse holding cage has bars spaced 7mm apart, a
pencil will just go between them. No mouse has yet got out between the
bars. Shrews on the other hand can, with ease...

According to the man from Rentokil, anything you can push a Bic Biro
through - say about 6mm diameter. Apparently their skull joints are
flexible, allowing them to pass through holes that are smaller than the
normal head size.

It's fascinating isn't it!

Tt's the rigidity of the skull which determines what size of hole - in
rodents at least, can be accessed.

I can't get my body through a hole my head would go though :-(

That's a worry. That's what I was supplied with to stop them - I have an
ornamental cast iron grill between the front door steps which help vents
the cellar and has much larger holes than that. But since covering the
inside with mesh a few years ago no signs of mice. Instead of near every
year previously. Perhaps it only stops adult mice, though.

nah, without protien the mouse would have became catabolic within
a few hours and it would have started to /lose/ weight.

someone put the mouse in the CU.

question is, why ?

But that's nothing. There was a case here a few years ago that made it
to the local paper. Occupants had noticed a strange smell in the
under-stairs cupboard. Transco could find no gas leak and suggested the
cause might be electrical. An electrician was called and found a dead
*snake* in the consumer unit.

But a snake in a CU. Now that is brilliant. You tell the customer that it is
probably nothing to worry about, open their CU and then tell them it is only
a dead snake that was causing the problem.

That process of checking that conductors or equipment that you are about
to work on and that you /think/ you've isolated *really* is dead. A
proper formal procedure (e.g. to comply with the EAW regs) involves
using a test lamp or voltage indicator and proving that the indicating
device itself is working both before and after the test.
