We have 6 cats and 1 dog.... 2 of the cats are my daughter's cats... she and her human family are living with us for a bit...
Anyway, about the cats... one thing I wonder about is......
Who is better trained... the cat, or the human?
Here is why I say that.... 2 of the cats are indoor-outdoor cats (I know it is better that they be indoor cats... but these two pretty much refused to transition to indoor when I changed the others to being indoor only).
Diablo, when he wants to go outside, he comes to me in the computer room and meows... and meows... I can meow back at him, and he gets more insistent if I don't get up and let him outside. Then, when he wants back inside, he comes to the computer room window and meows! So... who is better trained... the cat, for coming to me to tell me he wants in/out, or the human, for getting up when ordered and letting him in or out?
It is fun watching the interaction/ranking of the cats. Bugsy, our big black cat, is the top-ranked cat. Occasionally, Diablo challenges him. Below that is Smokey and Belle. I believe Smokey is below Belle, but has been very happy at that rank.
I'm not sure where Mouse fits in. (This is one of my daughter's cats... we started taking care of her a couple of years ago.. she was always hiding at their apartment.. long story.. she is a rescue and not comfortable around many humans, including their son. He is just a bit too fast and noisy for her. She (the cat) will scoot off if we move to quickly for her, also, but is quite a cuddler.) Anyway, when she came, she was obviously bottom. I think she is between Smokey (bottom) and Belle.... she and Smokey get along fine, but Belle and Mouse don't. I the past Mouse would guard different rooms and not let Belle in.... they do have a sort of "truce", but not a true relationship like Belle and Smokey, where they groom each other, or sleep next to each other. Belle and Mouse will tolerate being in the same room now, though.
Osita just came back into the family (the other one of my daughter's cats).... she was raised here, and has lived here on and off. However, she is used to being "top cat" at her house, so when she comes back into this house, she gets dumped at the bottom, and then starts battling her way back up.
It is just interesting to watch the cat dynamics, and who will tolerate what from whom!
