Felinids are a strain of Abhumans that reside on a very pimpish name for a planet; Carlos McConnell. They go by the scientific name Homo sapiens hirsutus. They are on the short list of 'tolerated abhuman strains' maintained by the Administratum, which means that at one point in the story of the Imperium someone high up (probably an Inquisitor with a furry fetish) decided they were a-okay and did not need to get purged (yet).
Thus ends the entirety of the canonical information on the Felinids. I wish I was kidding.
Judging by their name they might as well be Imperial Catgirls, if not full-on furries (hirsutus = hairy), although the idea on why humanity started growing feline-like traits is beyond the realm of contemporary science. Since almost nothing is known of them, nor their planet, the flood gates were opened for /tg/ to imagine up their relationship with the Imperium; as something only the Guys with fancy hats would have the permission to "Study" them. Although it would be quite the hilarity to vision a Space Wolf Wulfen chasing down a Felinid.
Speaking of Space Wolves, they may give an explanation as to why Felinids (and all abhumans in general) potentially exist. In Space Wolves fluff, there is a saying that there are no wolves on Fenris. Not to mention that it's implied that Fenrisian Wolves are former humans. And if we take into account the tech of the Dark Age, its quite possible that Felinids (and abhumans in general) are simply the descendants of human colonists who added and modified their genes to survive on the planets they lived on.
What their role in the Imperium is
Although almost nothing is known about the Felinids, we can speculate that they might be used as road (and book shelf) cleaners or construction workers or anything that has to do with civilian work, since they are never mentioned to be part of the military. Furthermore, due to their location on one planet, they might also be used as exotic dancers or sex slaves by your average Imperial Joe. "IF" they were in the Imperial Guard, then they could either be used as scouts, thieves or assassins, but this is mainly a stereotype of Cat-people so it might not be true.
There are three possibilities for Felinid biology, and they depend on their origin. First, as mentioned above, they could be the descendants of human colonists who altered their DNA to survive on their planet. That means we should expect more of an Imperial analogue to Catfolk, with specific biological changes depending on planetary conditions - improved night vision would be very probable, as well as claws, either optimized for speed, like a Cheetah, or for climbing, like most other cats. Other changes would very heavily depend on the cat or cats chosen - tiger felinids and lynx felinids would be fairly different, although both would probably have an unhealthy obsession with string.
Their scientific name, hirsutus, which means "Hairy" in Latin, could also suggest that they are Furries, although how hairy/furry their body could be is up for debate. But it must be remembered that even just a little hair would be hairy enough for the Imperium to call them "hirsutus" since they just need to be hairier than normal humans. This possibility has more credence based on the theory that Canis Helix was introduced to Fenrisians to make them hardier, resulting in latent wolf-like traits, some to the point of full wolf-like appearance. Though again, this isn't hard fact.
The second option is that given our own... fascination with catgirls, they could be a case of a high class member of society attempting to create the perfect Waifu, only to find out the Felinids did not like BEING the Waifu and eventually branched off, when their population became big enough, into another Abhuman race. This case would have the Felinds look more like the 10% on the graph down there rather since they were created with looks in mind, not functionality, just like dogs and cats on Terra in M2. In this case they would be much more human-looking, with only a few cat-like physical traits and mannerisms. Some fa/tg/uys have chosen to imagine them as catgirls with glam-rock hair, which given 40k's setting, is very likely. But seeing how grimdark this galaxy is, it can always be much worse.
The third option, of course, is that they're simply misclassified Beastmen, with the specific Beast of some sort of cat. Given the usual Beastmen aesthetic, that nearly guarantees a large cat was chosen - probably a lion or tiger, since they have the greatest reputation as "man-eaters" on Terra.
NOW WITH PROFILES AND RULES

Jaguar Squad (100 pts - Fast Attack):
Jaguars are characterized by black or very dark skin and fur. These abhumans are used as forward vanguards or assassins due to their natural affinity for stealth, by the few Guard Regiments that can afford these specialists. They are particularly fond of dipping their Jaguar Claws (extremely large monomolecular clawed gauntlets designed to separate flesh from bone with the ease of snapping one's fingers) in venom before deployment.
Unit Type: Infantry. Alpha Jaguar is (Infantry, Character). Unit Composition: 4 Felinid Jaguar and 1 Felinid Alpha Jaguar. May take up to 5 additional Jaguars for 20 pts/model.

- The entire Squad may replace their Stealth USR with Shrouded for 1 point per model.
- Cat's Eye: Felinids have the Night Vision and Acute Senses USRs, and Preferred Enemy (anything with Toughness and Strength 2 or less).
- Cat's Grace: Felinids move exactly as though they were Beasts, despite having the Infantry type. When hit by a non areal weapon a unit of Felinids must take a Beast Reflexis test wich give them a 5+ invulnerable save.
If you really want to field an army of catgirl guard, you'd better have an overabundance of free time, sculpting skill and greenstuff. Otherwise you're just SOL, because there's virtually nothing else to work with. No conversion bits, no kits from other games to convert, nothing. Not if you want an army of them. There are, however, plenty of individual catfolk models for RPGs and such, so Felinids could conceivably see the 40k tabletop as characters for Inquisitor warbands. Which, from a fluff perspective, is probably where their abhuman talents would see the best use anyway, as count-as death cult assassins or something.
Scratch all that, as of Fall 2018 the appearance of the Albedo Combat Patrol Miniatures Game has brought with it a cat conversion kit for 28mm models available from Sally 4th, so at long last you can finally have some proper Felinid Imperial Guard.
