Rusty is an Exotic, as is Patches. Exotics are actually short-haired Persians, but now, they are recognized as a separate breed. They have all the wonderful features of the Persians, but are easier to groom since they lack the very long, thick coats of the Persians.
These cats are known for their sweet personalities, and usually calm demeanor. They also are known to show greater attachment to their humans than the usual cat breed. But, there are always exceptions, and I know of many cats who are not pure breeds who show exceptional closeness to their humans. So, the myth that cats are always “standoffish” is just that: a myth.
