Penis
Domestic cats have barbed penises, with about 120–150 one millimeter long backwards-pointing spines. Upon withdrawal of the penis, the spines rake the walls of the female's vagina, which is a trigger for ovulation. Lions also have barbed penises. Male felids urinate backwards by curving the tip of the glans penis backward. When male cheetahs urine-mark their territories, they stand one meter away from a tree or rock surface with the tail raised, pointing the penis either horizontally backward or 60° upward.
King-Size Canary
The bird is emptied from the sack, to be revealed as scrawny and little. The bird tells the cat, "Well, I've been sick..." Disgusted with the tiny creature at first but still desperate, the cat gets a (literal) brainstorm when he sees a bottle of Jumbo-Gro plant growth formula on the shelf. Quickly he pours some of the formula into the bird and sure enough, the canary grows rapidly in size. But before the cat can take a bite, the bird is already over 10 feet tall. The canary takes advantage of his new height and beats up on the cat. The cat turns the tables on the bird and drinks the Jumbo-Gro formula himself, doubling in size until he is much bigger than the bird. He tosses the potion out of the window only for it to land in the bulldog's mouth. While the now giant-sized cat chases the slightly smaller canary through the side of the house, the bulldog guzzles down the formula. After a quick run around the block, the cat and canary wind up back outside of the house, where a now gigantic bulldog appears before them. The cat runs away in fear as the bulldog tosses the bottle of plant growth food down the chimney, where it rolls out of the fireplace and straight to the mouse inside the house. The dog leaps over the house and chases the cat into the city.
