Wound on my cat's neck, spider bite?

Welcome to TCS .... oh dear - that look's like a puncture of some sort - could be an infected spider bite or another type of bug OR did you cat get into a tiff with another cat ?? There is a lot of missing hair around the wound too. I would definitely take your cat to your vet for this. It also looks like it could become an abscess and your cat might need antibiotics for this.

It looks like a puncture bite from another cat..Does you cat go outside? or do you have another cat that this one could of gotten bitten from? I would have the vet take a look..It seems to be getting infected looking..

Not sure what that is.... I more inclined to say your cat has been shot by BB gun than that being a cat bite. Too big, too open, and only one instead of two..... To me, that matches a pellet shot/BB gun.
A kitty who has been shot by BB gun:

See how it looks similar?

Well.... My cats have bitten each other and none have ever lost hair either, so I can't answer that question..... But to me, personally, that does not look like a cat bite. IMHO a cat will not stop, twist the neck, then bite with only one fang, that deep, and have no signs of the other one..... no scratches, no tearing..... IMHO not a bite.... But again, that's me.....
The hair loss can be due to an abscess, maybe? That I can not answer..... Sorry
As far as the position..... You would be surprised how cruel people can be - including, getting your kitty and giving a close range shot right there.

I'm going to go with it looking like an abscess.  A vet should take a look at it to be sure.

Untreated, abscesses can get very nasty. Definitely get your baby to a vet on this one.

Yes, and the description sounds very typical, with a small central wound, a hard area around it, and the cat licking it, pulling out the fur.

 

Hair lose round an abcess is normal.  If he was mine he'd be on his way to the vets.   BTW I have seen abcesses from cat bits with only one puncture wound - my Havana used to fight a lot just after I moved to this house and whilst there was quite often a second mark if I looked really carefully, there was usually only one puncture.  He had short fine hair so it was easy to find wounds compared with a more average moggie coat.  I have a really yucky photo somewhere of the one he had over his eye one time, complete with hair lose!

My cat has the EXACT same thing on her back hind leg. First is was just discolored. Some hair was missing. Then as weeks went by it seemed there were puncture wounds or something..then they started to get just like what your picture is showing which makes me think SPIDER BITE. My cat does not flinch when it is touched and it does not seem to hurt her either. BUT..she also lost her fur in that spot those marks are in....and yes, I am sure it is a spider bit or something of that nature. IT CANNOT BE A BITE FROM ANOTHER CAT OR THE BITE WOULD HAVE SHOWN RIGHT AWAY. The puncture marks became bigger and opened up and got just like that on my cat as well. Did you take your cat to the vet and if so what did the vet say? I think it is a spider bite. Absolutely. I was bitten by a spider about three years ago....and the puncture did the same thing...it turned nasty. So...spider bite is my guess as well.

Linda, is your cat fully recovered?  Hope so, whatever it was.
