Torn Toenail in Cats

I noticed a really dry nail bed on my cats left front paw but it is only one (he won’t let me see his back ones though) and it is where the thumb would be. He also lost hair right in his ear crease and it is turning a crusty white, could these two be connected, but how can I treat his paw because it seems uncomfortable.

My polydactyly cat has a small split between her extra toe.
Should I just watch it to make sure it does not show signs of infection? What should I do?
I tried putting polysporin on but she wants to just lick it off.

I think my cat has torn her nail. The quick looks red but she wont allow me to get a good look at it. There is blood om a toy she was playing with but i initially assumed it was her baby teeth.

My mom cut my cat’s nail too short, so it went into the quick. But she didn’t cut it all the way through. I called my vet but she said to leave it alone, which I did but the little bit of nail got worse and worse. It’s been 2-3 days now, signs of more bleeding then stopping. I cut the little bit of nail that was just pushed out, and now the bottom of the nail feels like a loose tooth, but I’m not sure if it’s the quick or if it’s just blood. He won’t let me touch it, and he screams, but he doesn’t limp AT ALL, and he runs and jumps fine. What should I do.

My cat is outdoorsy and last night she came home limping in one paw. She has improved significantly overnight, but she's still limping from time to time. She let me have a close look at the paw (she's a very good girl) and I saw that one of her claws is slightly bloody and swollen. I saw no signs of infection and the claw looks okay to me, it's just the cuticle that seems to be damaged. I want to treat her at home as much as I can because going to the vet's stresses her out incredibly and she seems to be on the mend already. Should I do anything to the claw even though it looks healthy? I intend to clean the wound and bandage her paw if she lets me, but as she doesn't lick it any more than regular cleaning I don't want to push it.

My kitten hurt her claw and it seems to be getting infected, how expensive is it to have that taken care of? Or is there anything I can do at home to help it at least until i get paid in a week and a half?

My cat has torn a claw completely out and its infected. Can't get to vet til tomorrow. I have some enrofloxacin. Will this help? I've cleaned all the dried blood and pieces of his claw out. As soon as I cleared all the debris out, a nasty smell was evident.

We let our cat be outdoors occasionally and tonight he came in limping. After taking a look at his paw, it seems he tore his nail. There wasn't much blood and whatever bleeding there was, stopped before he came inside. It looks like it's torn up on the bottom side of the nail. So far no infection and the limp is minimal. We put hydrogen peroxide on the toe and gave him some leftover amoxicillin from his last visit to the vet (2 weeks ago). Should we just watch and wait or do something more?

I couldn't find a place to post my follow up questions.

Follow up questions: I see that it says to trim the toenail at the tear to avoid infection. Our cats tear is at the base of the nail so we would have to cut the whole nail off. Is it safe to cut off the whole thing? And how long should we expect him to have a limp before being concerned? Thanks!
