Praise then darkness, and creation unfinished

That would depend on precisely what the structure of the fur was. While "fur" is one of Dr. Jack Cohen's "four univeral F's" -- the four things that have derived independently multiple times over Earth evolution, and thus might reasonably be expected to show up in extraterrestrial life -- the "fur" structures are very different in mammals, tarantulas, honeybees, pussywillows, and kiwis. Now most of those do involve some sort of pore, on Earth, but I could imagine a fur being a direct outgrowth of skin or exoskeleton, rather than poking through.
