Meet Veronika... the back-scratching cow of Austria!

What's brown and sticky? This cow, of course!

Meet Veronika... an Austrian cow who uses sticks, rakes and brushes to scratch herself.

Her use of tools is making scientists rethink what cattle are capable of, as the discovery suggests they might have greater cognitive abilities - or intelligence - than previously thought.

Read on to find out more about Veronika, and some other clever animals that also use tools...

This kind of tool use is rarely seen in the animal kingdom and has never been documented in cows before.

Veronika even uses both ends of the same object for different tasks!

But the researchers from the University of Veterinary Medicine in Vienna don't think Veronika is alone.

They think other cows may have similar abilities, and humans just haven't noticed before.

Dr Antonio Osuna Mascaró, one of the researchers on the study, said: "What this tells us is that cows have the potential to innovate tool use, and we have ignored this fact for thousands of years," he added. "It's shocking that we're only discovering this now."

So what other animals use tools in their daily life?

Read on to find out.

It's probably not surprising that chimpanzees - who share around 98% of our DNA - use tools just like humans.

The primates have been known to use sticks to dig out food, like larvae from tree bark and honey from bee hives

They also use rocks to crack nuts to eat and crush up leaves to use as sponges.

Sea otters are known to use rocks as tools.

They'll use rocks, shells and even rubbish like bottles as hammers to smash open hard foods, like crabs, mussels and snails.

This lets them eat foods which they wouldn't be able to open by just using their teeth.

Some bottlenose dolphins in western Australia have been found to carry sponges on their noses.

Scientists believe they pick up sponges from the seafloor and then use them as tools to help them hunt fish.

By biting onto the sponges and "wearing" them on their snouts, they can protect their noses whilst stirring up sand on the rocky seabed, which helps them to uncover the fish that hide underneath.

These New Caledonian crows make hooks from bits of plants.

It means they can stick it into places like tree holes to capture their prey more easily.
