like why bird usually discover

Do you have a dog, a cat or a bird at home? Do you watch them carefully?
Scientists have found that cats, dogs, and even goldfish are left-handed or right-handed. These scientists work in Queen's Belfast University. They said that pets are left-handed or right-handed people. As we all know, it is important for animals to be good at getting food. Some like to get food with their right hands, but some like to get food with the left hands. That's the animals are left-handed or right-handed.
The scientists have that male cats and dogs are almost left-handed, and female cats and dogs are right-handed, because their work in everyday life is different.
People think that left-handed people are better at languages; some even think that left-handed people are smarter. When it goes to animals, it makes animals act more quickly.
