Sorry about Mog, that's a real worry for you. I hope he comes back home at some point safely. New kitten is lovely looking, nice one for homing a rescue kitten too.
On dogs and cats you need to occasionally intervene but we had lots of dogs and cats when I was growing up (including gun dogs as well as terriers) and we never had a dog and cat related incident. We homed strays / feral for the rescue place in our stables (my father loved cats) and they would occasionally emerge pursuing a dog, but we didn't have any other issues.
We also had a dachshund and a stray who loved each other hugely, they were 18 and 17 when they died and when the dog went the cat died a month later, he just missed her.
I think you have to prove to whoever is already at home that you still love them lots and will pay attention to them. Sometimes the conflicts are jealousy, particularly if a dog has been a lone pet.
