This crag, in the Squirrel Wood, is a basaltic formation, one of several in this area (the most impressive of them is the
Image; see also
Image and
Image).
Cat Craig is named on large-scale OS mapping, and is visible from the public footpath that leads through the woods, but it is rather overgrown, and obscured by trees.
In his book "The Parish of Strathblane" (1886), J G Smith mentions this crag by name, linking it to a battle that occurred in 750 (and which is often called the Battle of Mugdock) between the Picts and the Britons. He explains "Cat Craig" as meaning "Battle Rock", and he links various other place-names nearby with events in the same battle (I quote that passage below).
My own view is that it is highly unlikely that such a detailed account of the ancient battle has come down to us in tradition; mainly for that reason, I consider it much more likely that Cat Craig simply means "crag of the cat" (probably the wildcat, Gael. "cat fiadhaich"). On a similar theme, there is a
Image nearby, whose name probably means "crag of the badger".

Other places Smith mentions in his account of the Battle of Mugdock include the
Image;
Image, which certainly pre-date the battle of 750 by very many centuries; "Blair's Hill", which is at
Image; and "Alreoch", which is at
Image Smith gives explanations for these place-names that seem to tie in well with the traditions, but which do not stand up to modern scrutiny (I point this out because they are still sometimes quoted: see
Image).
While his description of the battle and his place-name etymologies are unsound, they do at least serve as an interesting record of the prevailing beliefs of the time. The relevant passage, which I cite only for its curiosity value, is as follows:
"The field of this battle can be traced with but little difficulty. The Cymric army was posted on the high ground on Craigallian – then part of Mugdock – above and to the east and west of the Pillar Craig, with outposts stationed on the lower plateau to the north, and there awaited the Picts, who came up Strathblane valley through Killearn from the north on their way to the interior of Cumbria. Near the top of the Cult Brae, in a line with the Pillar Craig, there is a rock still called Catcraig, i.e., Cadcraig, meaning the "Battle Rock," and in their efforts to dislodge the Cymric army, whom they could not leave in their rear to fall upon them when they had passed, the Picts doubtless had penetrated thus far and here the battle began. It was continued all over Blair or Blairs Hill, i.e., the "Hill of Battle" – the rising ground on Carbeth Guthrie which commands the valley of the Blane – and Allereoch or Alreoch, i.e., the "King's Rock," was certainly so named from being the place where King Talargan fell when the defeated Picts were being driven back to the north-west. The standing stones to the south-east of Dungoyach probably mark the burial place of Cymric or Pictish warriors who fell in the bloody battle of Mugdock."
