Brownie might have gone to the movies and gone home again without anyone ever having been the wiser, if there had not been a film shown that night that no regular dog could look at and not bark.
"Oh, look at the big cat!" whispered Sister excitedly.
Surely enough, a large cat sat on the fence, and, as they watched, a huge collie dog, with a beautiful plumy tail, came marching around the corner.
He spied the cat and dashed for her. She began to run, on the screen, of course. The audience in the movie house began to laugh, for the dog in his first jump had upset a bucket of paint. The people in the theatre were sure they were going to see a funny picture.
But Brownie had seen the cat, too. He knew cats, and there were many in his neighborhood he meant to chase as soon as he was old enough to make them afraid of him. He scratched vigorously on Sister's blouse and whined.
"Ki-yi!" he yelped, as though saying: "Ki-yi! I'll bet I could catch that cat!"
Barking shrilly, he scrambled out from Sister's middy, shook himself free of her arms, and tore down the aisle of the theatre, intent on catching the fluffy cat.
"Ki-yi!" he continued to call joyously.
"Brownie! Here, Brownie!" called Sister frantically. "Brownie, come back here!"
The theatre was in an uproar in a minute. Ladies began to shriek that the dog was mad, and some of them stood upon the seats and cried out. The men who tried to catch Brownie only made him bark more, and the louder he barked the more the ladies shrieked. Finally they stopped the picture and turned on the lights.
