All I can say here is, I'm an animal lover myself, I got a Dog and 2 cats, the dog however, smaller then BOTH the cats and hes a happy go lucky little guy, the cats, are well.....territorial to say the least, but they all 3 of them, protect any one of us outside! We take the dog for walks, the cats follow not far behind over the entire walk, no matter where it is, outside a lone the cats don't seem to stray far from home!
I can see this as Cats really are predators...BUT to be able to pounce a dog the size seen here for the size of that Cat, the Cat must have clawed the **** outta the dog to spook it as otherwise that dog may have eaten that cat for a snack!
BRAVE cat, he loved his owner, and its seen here who the cat truly loved!
