Looney Tunes

A homeless cat (Claude Cat) searching for food is harassed by the playful antics and barking of an energetic pup (Frisky Puppy). Frisky repeatedly sneaks up behind the poor tabby cat (who hates the dog) and scares it into jumping vertically when it barks. After Claude finally silences the pup, he encounters a larger dog, whose bark has a disastrous effect. Tweety Bird has two lines. Can you guess what they are?
