LOL! I thought Garfield was a cartoon!
If those are actual cats, they’re too fat to attack even a dust-bunny.
There are a lot of animals that are aggressive and prone to attack humans, including a number of breeds of dogs. However, only a few kinds are big and strong enough to do serious damage or kill.
Most dog *bites* are from small dogs such as miniature poodles and little terrier breeds, but most injuries/deaths involve pit bulls and rottweilers. It doesn’t make them more “vicious” as a breed than others, but it does make them more dangerous, and pretending otherwise can be fatal.
