Dogs vs. Cats

I have both dogs and cats, the fight breaks down to specific variables, as i have seen my dogs win and my cats win.

Variables are as follows:

Size of dog vs size of cat
Breed of dog vs breed of cat
fight in dog vs fight in cat
dogs age vs cats age
dogs health vs cats health

I will tell you one thing i have maine coon's and 4 pit bull's, the fight in each of them commands respect. I have seen one of my maine coon's beat the shit out of one of my pit bulls. I have also seen my pit's tear my maine coons apart, at the end of the day they reconcile their differences as they have lived around each other most of their lives. It its difficult to watch a maine coon climb on to a dogs back and tear into his eye balls and not go and stop it, just the same as it is difficult to watch a pit bull force a large maine coon down onto it's back and lock onto it's neck and force it into submission. Luckily though as stated before they are more like kin, they have grown up around each other so they haven't killed each other (knock on wood)
