Supposedly, one of the ways to avoid a Real-Life wolf attack in the wilderness is to linger near a fire and/or brandish fire in front of their toothy snouts; there's just something that wolves and their little lupine eyes just don't like about the brightness and erratic movement of fire, and it tends to keep them at bay or spook them off. But I've never been attacked by famished wolves, so I wouldn't know firsthand. But hey...it worked in Darklands, right?
On the other hand, there are some stupid dogs around here who would roll around in an ember pit (and burn themselves quite badly) if those pesky humans would let them, and I doubt that felines would be deterred by fire at all. I've burned rubbish and deadfall in our backyard after dusk, and the three cats who live under our house will walk right up to the bonfire and check it out. So I definitely wouldn't code any crag cats to avoid campfires.
