I had two solid black cats as fosters so I know how hard they are to adopt. The younger of the two just died of a blood clot and the other is having urinary issues, so he needs some "draino" work on his plumbing. If you google it, black cats generally are the best friends you will ever have. We had one for some 15+ years. It's nice to know the story of Lenny and Carl.
Do you realize how hard it is to keep kittens that young alive? Without their mom it is nearly impossible. Are they really bonded to you? Or are they turds? I'd guess bonded
Congratulations to you and your wife.
