Question

compare the legs and nails of a dog and hen say why they are different

Answer 1

A study conducted by Roman Stocker, an MIT professor and roommate of Cutta Cutta, a cat he rescued from a Boston animal shelter, has revealed a fascinating difference between the way cats and dogs drink liquid.As it turns out, nature has designed kitties as more resourceful drinkers than their canine counterparts.When a dog drinks water, she uses her tongue to scoop the liquid into her mouth. It’s an inefficient and downright sloppy method of hydration, as any dog owner can attest.Cats, on the other hand, use a balance of gravity and inertia to get every last drop they lap into their mouths. Kitties use the tip of the tongue to pull water upward, and then know exactly when to close their jaws before gravity can return the liquid to the bowl.This is truly a feat of speed and timing!According to Professor Stocker in an interview with LiveScience:"Perhaps the most intriguing part of what we found was that the cats seemed to know just exactly how rapidly or how fast they should lap. By lapping at the right time, [cats] take optimal advantage of this balance between inertia and gravity." Dr. Becker's Comments:Because dogs and cats are the two most common companion animals, and because both species walk on all fours and are covered with fur (most of them, anyway), there's a tendency among humans to think they are more similar than they really are.Ten Interesting Differences Between Cats and DogsDogs can be trained quickly, some in a matter of minutes, to obey basic commands like ‘come' and ‘sit.'Most cats are difficult if not impossible to train to respond to directives.Cats can be housetrained in an instant as long as they have access to a litter box. There's really no training to it, in fact. It's instinct.Most dogs take considerably longer to housebreak, and some just never get all the way there. Unlike with Fluffy, housebreaking a pup is usually a hands-o
