If my kids carried an a baby animal by the tail and I corrected their "incorrect treatment" of said pet and they continued with the "obnoxious treatment" of kitten, and kitten defends itself, I would tell my kids that they get what they deserve. But I don't allow my kids...AT ANY AGE...to mistreat animals anymore than I would allow them to touch a hot stove or stick pins in their eyes. So if your child mistreats an animal, correct their behavior. If you don't know how, think about what you would do if said child was getting near a hot pot of spaghetti to stir it.
Having "barn cats" does not mean you have pet cats. They are likely feral, unsterilized, never vaccinated and unlikely they get checked for parasites. Feel free to correct me if I am incorrect on my assumptions.
It's also clear to me that you and I think differently about animals because dogs are "pack animals" and your FAMILY DOG'S family is his pack...that'd be you and I don't think it's right to keep an dog outside all the time anymore than I think it right to chain a dog. Get a pet, let it inside the house and pet him and brush him...give him CLEAN, fresh water and food everyday in clean bowls.
So back to the kitten, now a cat, that you hate, that you allowed your daughter to mistreat. The likely reason KITTEN attacks your children is because your kids are mean to HIM and he has to defend himself. Kittens love to be played with, gently, tickled and snuggled, not having "his" tail pulled because that is how your child carries said pet. You don't sound like you are too nice to "him" either...it sounds like you have had KITTEN quite a while and still refer to KITTEN as "IT". Okay, so you hate or dislike cats intensely and choose to have them live in barn without medical treatment or probably food, fresh water and parasite inspections/treatment, but as rodent control. You wouldn't be first. For Christ's sake, if you don't want KITTENS, spend a few dollars to FIX the cats in your barn ! I'm assuming there might be more kittens around your property because most female cats have a litter of a few even but maybe these were eaten by local predators or hit by a car crossing the road.
As far as mistreated KITTEN, whom now is likely scared of your child, and is likely borderline unsocialized, do not release it OUTDOORS to get sick with a horrible disease, hit by a car, killed by a coyote or fox, live in your barn as rodent control and to have MORE KITTENS, please contact a rescue group !
As a matter of fact, I will help you get this kitten away from you and your family ASAP.
Please email me with your city and I will HELP YOU find a rescue group that will take this cat, sterilize cat so he/she cannot further reproduce MORE UNWANTED pets and find a "good" home for kitten.
My kids learned how to treat animals nicely when they were about 1 year old because my there was no way my pets signed up to have their tails pulled by an undisciplined child. When ,my cats 'hissed' at my kids, I explained to my children..."That is how YOU know that Kitty doesn't like what you are doing, so stop." I never corrected kitty and now my children are absolutely AMAZING AROUND PETS ! They know to treat a pet by petting gently and kindly. They know to ask to pet someone else's pet. They know that when pet walks away...that pet wants to be left alone and they are not to chase or harass.
And no, I disagree that a cat is going to yowl 17 weeks old because she is in "heat". Kitten is still young enough to be socialized and find a good, loving home where he can be handled appropriately.
As far as daughter, correct her behavior and assure her that if she mistreats animals, they will retaliate. See, they don't have words to say "Stop, that hurts." They will bite or scratch because that is how they express disdain for being mistreated. That is how "kitten" corrects your child ! As far as daughter's wounds, put some ointment on the wounds, bandages, whatever. Instruct her to stay away from the cat...or she will be disciplined by both you and kitten, unless she is willing to treat little innocent kitty nicely.
Do you have a litter box and food? Does kitten have a blanket in pet carrier at least?
It doesn't sound like your husband gives a rats patootie about the kitten either so when you find a rescue group to take kitten, he likely won't care. He's not a responsible pet owner because a responsible owner ensures that kitten is happy, kids are learning how to treat pets responsibly, and that pet has all she needs including vaccinations and appropriate nutrition. They also ensure that "pet" has appropriate bedding...not some hard, cold crate to stay in 8-12 hours per day even though there is supposedly a loving family at home. See, crating is really for when you aren't home, or at night, and I don't know of too many people that crate cats unless cat is sick.
Again, feel free to send me an email or your city and I will HELP you find a rescue group to ensure kitten will live on, vaccinated and sterilized.
But, who is that kitten's mother??? Is it your barn cat? Consider having your barn pest control pets "sterilized". You want to do both male and female because you don't want the male ROAMING and impregnating another female. And they will. They can smell a female in heat a few miles away !
So again: Feel free to contact me with your city and I will assist you in finding a rescue group for that sweet kitty. Please consider having your barn pets sterilized or there will be more unless you want to feed the local coyotes or owls with kittens, but that isn't cool for the kittens.
FYI: I know some rescue groups local and they may know of rescue groups in your area. But I did just a basic preliminary search on "kingwood" assuming that is where you are located. I found this group, albeit, I know nothing of them. Again, feel free to contact me because I want to HELP this kitten find a safe and loving home. But here is a local Texas group:http://www.adoptapet.com/adoption_rescue/74984.html

Make no mistake: This is NOT the cat's fault.
