Cats are useful because they are pest controllers who hunt and kill rodents and insects.

For example, the Forbidden City in China "employs" hundreds of cats who live in the fortified city to keep the rodents out and protect the historical artefacts from rodents munching on them - they get paid in free food, free housing and free medical.

Stroking animals, such as cats, has been scientifically proven to reduce stress and anxiety, which is a benefit they have to humans.

They are also harmful because their natural hunting instinct puts a lot of endangered species at risk. For example, red squirrels are endangered in Europe and the UK, but that doesn't stop wild or stray cats munching on them for breakfast. Too many cats in one area or house can also cause hygiene concerns, since there will be a lot of fur, vomit and faeces build up.
