Is it necessary to note that a rat is not a mouse? Or a squirrel? Yet it seems to be news that the dormouse is not a mouse.
Admittedly, if rats were called ratmice, there might be more confusion.
And rightly so! But there are 29 species of dormouse. What is going on?!
There are a couple of things. First, dormice look like mice—at least if you don't look closely. If you look at their tails, they start looking more like chipmunks. And genetically, dormice are a lot closer to squirrels and chipmunks than they are mice and rats.
The more important reason the dormouse have this name is that it was originally called dormeus—which is an old Norse word for "sleepy." Over time, the word became dormouse, although why "dormice" is the only accepted plural is unclear to me.
Most interesting of all, dormice were named "sleepy" because they hibernate six or more months per year. This might also explain why they aren't taken as pets. Or it could be all the stuff that starts with "M."
Or even better:
'Suppose we change the subject,' the March Hare interrupted, yawning. 'I'm getting tired of this. I vote the young lady tells us a story.'
'I'm afraid I don't know one,' said Alice, rather alarmed at the proposal.
'Then the Dormouse shall!' they both cried. 'Wake up, Dormouse!' And they pinched it on both sides at once.
The Dormouse slowly opened his eyes. 'I wasn't asleep,' he said in a hoarse, feeble voice: 'I heard every word you fellows were saying.'
'Tell us a story!' said the March Hare.
'Yes, please do!' pleaded Alice.
'And be quick about it,' added the Hatter, 'or you'll be asleep again before it's done.'
'Once upon a time there were three little sisters,' the Dormouse began in a great hurry; 'and their names were Elsie, Lacie, and Tillie; and they lived at the bottom of a well—'
'What did they live on?' said Alice, who always took a great interest in questions of eating and drinking.
'They lived on treacle,' said the Dormouse, after thinking a minute or two.
'They couldn't have done that, you know,' Alice gently remarked; 'they'd have been ill.'
'So they were,' said the Dormouse; 'very ill.'
Alice tried to fancy to herself what such an extraordinary ways of living would be like, but it puzzled her too much, so she went on: 'But why did they live at the bottom of a well?'
'Take some more tea,' the March Hare said to Alice, very earnestly.
'I've had nothing yet,' Alice replied in an offended tone, 'so I can't take more.'
'You mean you can't take less,' said the Hatter: 'it's very easy to take more than nothing.'
'Nobody asked your opinion,' said Alice.
'Who's making personal remarks now?' the Hatter asked triumphantly.
Alice did not quite know what to say to this: so she helped herself to some tea and bread-and-butter, and then turned to the Dormouse, and repeated her question. 'Why did they live at the bottom of a well?'
The Dormouse again took a minute or two to think about it, and then said, 'It was a treacle-well.'
'There's no such thing!' Alice was beginning very angrily, but the Hatter and the March Hare went 'Sh! sh!' and the Dormouse sulkily remarked, 'If you can't be civil, you'd better finish the story for yourself.'
'No, please go on!' Alice said very humbly; 'I won't interrupt again. I dare say there may be one.'
'One, indeed!' said the Dormouse indignantly. However, he consented to go on. 'And so these three little sisters—they were learning to draw, you know—'
'What did they draw?' said Alice, quite forgetting her promise.
'Treacle,' said the Dormouse, without considering at all this time.
'I want a clean cup,' interrupted the Hatter: 'let's all move one place on.'
He moved on as he spoke, and the Dormouse followed him: the March Hare moved into the Dormouse's place, and Alice rather unwillingly took the place of the March Hare. The Hatter was the only one who got any advantage from the change: and Alice was a good deal worse off than before, as the March Hare had just upset the milk-jug into his plate.
Alice did not wish to offend the Dormouse again, so she began very cautiously: 'But I don't understand. Where did they draw the treacle from?'
'You can draw water out of a water-well,' said the Hatter; 'so I should think you could draw treacle out of a treacle-well—eh, stupid?'
'But they were in the well,' Alice said to the Dormouse, not choosing to notice this last remark.
'Of course they were', said the Dormouse; '—well in.'
This answer so confused poor Alice, that she let the Dormouse go on for some time without interrupting it.
'They were learning to draw,' the Dormouse went on, yawning and rubbing its eyes, for it was getting very sleepy; 'and they drew all manner of things—everything that begins with an M—'
'Why with an M?' said Alice.
'Why not?' said the March Hare.
Alice was silent.
The Dormouse had closed its eyes by this time, and was going off into a doze; but, on being pinched by the Hatter, it woke up again with a little shriek, and went on: '—that begins with an M, such as mouse-traps, and the moon, and memory, and muchness—you know you say things are "much of a muchness"—did you ever see such a thing as a drawing of a muchness?'
'Really, now you ask me,' said Alice, very much confused, 'I don't think—'
