Until relatively recently there was no well established word for a baby hedgehog. Although the word kit had occasionally been used, and sometimes pup or piglet, most books about mammals just called them `baby’ or `young’ hedgehogs.
However, by the early 1990s the word hoglet (or sometimes hedgehoglet) had been introduced, and this word seems to have been in general use among those with an interest in hedgehogs since at least the mid-1990s.
Isn’t that precious? Not really. How would you feel if you didn’t have a name? You wouldn’t be too pleased if people just kept calling you by other peoples’ names, or by some generic term. I bet those hedgehogs were pretty pricked off. Oh my clever clever wordplay.
Look at this jubilant hedgehoglet! Well, it is either jubilant or tired. Your guess is probably not as good as mine.
