HELP! My cat has 3 holes in her shoulder?

Hi, I'm new here, I've been reading from a distance, I've decided to join in! I rescued a pregnant cat off the streets recently. She has THREE holes in her left shoulder, I can see through them. She has had the kittens, the kittens are all rehomed besides the one I'm keeping. I bought medicine and put it on her, the holes healed up and new skin was there. I think she keeps licking them open. Its draining with a bit of blood in it? What in the world could this be? There is no knots there, just holes. When I wipe it off she meows like it hurts? It's not bot flies either. I don't know her past life. I don't know where the holes came from, they are a bit smaller than a dime? Please help?

Thank you for rescuing this cat!  Have you taken her to a vet?  Can you make her a cone to wear while the wounds are healing?

She should also be spayed now that the kittens are weaned.  

Thank you for taking this momma kitty into your home!

Cats will lick and lick and then lick some more to keep an area clean, that will cause it to take a while to heal.

We have several instances of cats fighting or finding cats with puncture wounds. Sometimes they are just holes in a few layers of the skin and other times the skin actually pulled away and its thru so that you can see muscle tissue and allowed for what the vet called a "tunneling" in between the tissue for nasty infection to set it.

Unless it was just a tiny scratch we errored on the side of caution and took them in and they were typically put on broad spectrum antibiotics. Punctures like that aren't always caused by fighting but the percentage is high and the chance of infection is even higher.

We also had experience with bot flies on a chipmunk, I can tell you that we swore up and down that there was no larva in there. How could we not see one of those huge ugly things in such a tiny critter? It wasn't until it stuck it's gross little head out that we could determin it was a larva and work towards removal. They are super hard to see.

I do like the idea of a cone or something to deter her from accessing the area to allow it to heel, but there could also be some reason why she continues to keep the area draining, only a vet can determin that for you.

Good luck with her and your new kitten!

The first thing I thought of was BB pellets. Please do take her in to be seen. As the others have said, antibiotics at least are a good idea. 

Thank you guys! Taking her in was my pleasure. If I didn't she would have died during labor. She is MUCH healthier now! I Havnt got to take her to the vet yet. I am 7 months pregnant myself, plus my 4 yr old son so vet expenses are almost impossible for me at this time. I did contact my local shamrock Foundation and they are going to cover everything for a small fee and they are going to fix her for me as well. I appreciate them. Yes a cone sounds like a great idea, because they keep healing over completely and she licks them back open. I'm just baffled at what this could be. I'm in Louisville Kentucky and I'm pretty sure bot flies are not common here.
