I have two sheltie boys and five cats. My pups are 9 months old, and the cats are 10 months, 4 years, 5 years, 7 years and 14 years (most of these ages are guesses besides the 10 month old, they're all rescues).
Initially my two boys were very nervous of the cats, they were curious but they learnt each of the cats personalities pretty quickly and how to interact with them.
10 month old Garfield: They're totally fine with him, as he's totally fine with them. They play together sometimes, but they seem to have a mutual understanding that they mean each other no harm and just want to have a little fun. What helps is that they've all grown up together, so they've been used to each other from the start.
5 year old Milly: She is terrified of almost anything and she can be seemingly aggressive, but it's only out of fear. She is very defensive and hisses at them easily. The pups hate her, or possibly love her... but for the wrong reasons. She likes to run, and they like to chase. Often they'll growl-bark at her as they chase her up the stairs. I often feel really bad for her, she's a cat who likes a quiet/calm home, she finds it difficult to move from one area to another if we have let the dogs free roam of the house for a certain time of the day.
Our oldest cat Sox is really lazy, the pups don't mind him at all, they often sleep with him. Though sometimes when Sox has had enough of their messing he will let the pups know and they respect that.
Shelties are smart (I think a lot of us here are aware of this
) and largely I have found they treat the cats much how they have been treated in return. You say your two oldest cats want nothing to do with Mia, how is that displayed by them?
