Yammy's pet dog, Kukkapuro, was supposedly an Arrancar, though, when I look at him, or the small, lizard-like Hollow in ep145 (@19min), I can't help but wonder if all Hollows were once human Plusses. Most Hollows feed on Plusses, or other Hollows, but Uryu suspects that the smallest Hollows simply absorb the condensed Reishi from the air in Hueco Mundo. This is pure speculation, though, and nothing substancial.
