Free 4 Month Old Black Male Kittens to Good Home

I found six kittens in late November, abandoned by my apartment complex dumpster. I was able to successfully find homes for three of the kittens, but the three remaining black males have not had any luck finding a home. I already have three cats, including a stray I took in last summer, and one dog, so I cannot keep the three black males. I have called every rescue in the city, and no one is currently accepting kittens since it's kitten season now. I desperately need help. They're incredibly sweet and healthy, purr constantly, and I do not want to drop them off at the shelter because I fear they will get put to sleep. I have had several people say they would take one, then back out and not end up wanting them. I am willing to travel anywhere in the state to make sure they have a good home. They have interacted well with my other cats and my dog. If you would like a sweet four month old black kitten, please reach out. Or, if you know of any rescues currently accepting cats, please let me know. I feel awful that I can't find homes for them.
