My mom cat carries a kitten to my bad cat for him to take care of

Our family is filled with cats who love each other incredibly. For some time, my bad cat and mom cat lived separately while we were taking care of the kittens. Now they are back together. Mom cat always tries to be closer to bad cat and always gives him something. She takes one kitten and brings it to him, allowing the father cat to take care of it. Then mom cat takes the kitten in her mouth again and carries it to the cat's home. The kittens have already grown up and they want to teach them how to walk and climb. Carrying a small kitten in her mouth is something that mom cat often does when the kittens are small. But even when they grow up, she carries them back to their place, or vice versa, she moves them to where she wants to show something to the cats. bad cat is wearing a kitten in her mouth
