Mr. Blaine, in his excellent and useful work, the "Encyclopædia of Rural Sports" a book no sportsman should be without thus discusses the origin of the domestic cat compared with the British wild cat:

"We have yet, however, to satisfy ourselves with regard to the
origin of the true wild cat (Felis catus, Linn.), which,
following the analogies of the Felinæ generally, are almost
exclusively native to countries warmer than our own. It is true
that occasionally varieties of the Felinæ do breed in our
caravans and menageries, where artificial warmth is kept up to
represent something like a tropical temperature; but the
circumstance is too rare to ground any opinion on of their ever
having been indigenous here at least, since our part of the
globe has cooled down to its present temperature. It is,
therefore, more than probable that both the wild and the tame cat
have been derived from some other extra-European source or
sources. We say source or sources, for such admission begets
another difficulty not easily got over, which is this, that if
both of these grimalkins own one common root, in which variety
was it that the very marked differences between them have taken
place? Most sportsmen, we believe, suspect that they own one
common origin, and some naturalists also do the same, contending
that the differences observable between them are attributable
solely to the long-continued action of external agencies, which
had modified the various organs to meet the varied necessities of
the animals. The wild cat, according to this theory, having to
contend with powerful enemies, expanded in general dimensions;
its limbs, particularly, became massive; and its long and strong
claws, with the powerful muscular mechanism which operated on
them, fitted it for a life of predacity. Thus its increased size
enabled it to stand some time before any other dogs than
high-bred foxhounds, and even before them also, in any place but
the direct open ground. There exist, however, in direct
contradiction to this opinion, certain specialities proper to the
wild, and certain other to the domestic cat, besides the simple
expansion of bulk, which sufficiently disprove their identity. It
will be seen that a remarkable difference exists between the
tails of the two animals; that of the domestic being, as is well
known, long, and tapering elegantly to a point, whereas that of
the wild cat is seen to be broad, and to terminate abruptly in a
blunt or rounded extremity. Linnæus and Buffon having both of
them confounded these two species into one, have contributed much
to propagate this error, which affords us another opportunity of
adding to the many we have taken of remarking on the vast
importance of comparative anatomy, which enables us to draw just
distinctions between animals that might otherwise erroneously be
adjudged to be dependent on external agencies, etc. Nor need we
rest here, for what doubt can be entertained on the subject when
we point at the remarkable difference between the intestines of
the two? Those of the domestic are nine times the length of its
body, whereas, in the wild cat, they are little more than
three times as long as the body."
