There's this cat near my house that has gradually (over several months) become semi-domesticated. Yesterday I noticed it limping and, when lying down, licking its paw (right foreleg) more than usual. Today I was able to observe it from up close and take some pictures:
Does this have to be treated by a vet or at home? The reason I ask is that this is still very much a feral cat. Despite coming inside the house to eat and nap (for a very limited time), it doesn't allow me to pick it up or sometimes even to pet it, and there's no way I'd be able to take it to the vet or do anything to its paw (to treat it) without tranquilsing it (if that's even normal). Please let me know if I should give more details.
Some minor details: In this picture it's sleeping on a doormat (which I've laid out for the cat to sleep on and is not used in any other way) and that small white object near its paw in the first picture is leftover food. Like I said, it spends a very short time indoors, and on some days does not come by at all, so it's still very much an outside cat.
Edit: The black patch that @Elmy points out in the comments indeed appears to be pigmentation, based on this picture from last month (March 11), when the cat was completely alright (it wasn't limping or licking its paw too much or anything of the sort):
