Do all felines purr?

Tons upon tons: the heaviest animals reach crazy numbers. Here are the maximum weights in the animal kingdom.

In general, the absolute heaviest animal is the blue whale, whose average weight is around 110-150 tonnes (the heaviest ever recorded even reached 199 tonnes!).

In the ranking, however, we have only considered terrestrial animals or animals that have both terrestrial and aquatic habits. Browse the photo gallery to find out more.

A purring cat is not always a positive sign, and just like other signs, it is often misunderstood.

Cats are wonderful animals, but can often be difficult for people to understand, especially when it comes to interpreting their mood.

The signals a cat sends can easily be misunderstood, which can lead to incorrect interactions with the animal.

In this photo gallery, we explore some of the facial expressions and cat behaviours that are often misinterpreted, to help cat owners and lovers better understand their kitty and establish a harmonious relationship with them.

Parasites are a constant concern for anyone with pets. Fleas, ticks and mites can cause discomfort and health problems for our four-legged friends.

It is essential to take preventive measures to protect dogs and cats from these unwanted pests.

Here are five valuable tips to protect your pets and keep your home environment safe and comfortable.

Sea turtles are a superfamily of Testudines adapted to marine life. Thanks to the elongated shape of their bodies, which are covered by a robust shell (or carapace), and the presence of 'legs' turned into flippers, these turtles have adapted perfectly to marine life.

They are among the oldest tetrapods on Earth, but in recent decades, due to climate change in the seas, dwindling food resources and pollution of the seas, they have become an endangered species in need of protection by the international community.

It is undeniable that human hunting has also contributed to bringing this species to the brink of extinction. Perhaps by knowing more about this wonderful animal, we can contribute to its worldwide repopulation.

Immerse yourself in the mysterious world of chameleons, fascinating and incredibly adaptable creatures. 

With their vibrant colours and camouflaging abilities, these animals never cease to amaze. 

Follow their adventure as they camouflage themselves among the leaves of their habitat, becoming invisible to the eyes of predators. But their skills don't stop there: discover how they manage to change the colour of their skin to communicate, court or defend themselves. 

Let's discover together some interesting facts about chameleons that will make you reflect on the extraordinary diversity of nature.

There are many species in nature that are truly dangerous, but some are distinguished by their strength, predatory abilities and their natural reflex to attack to protect themselves or to hunt.

Climate change affects many aspects of our lives and also the lives of animals. The situation is also getting worse for the oceans, with global warming altering ecosystems and forcing animals to change their habits.

For many animals, this also means deciding to abandon their habitat and move elsewhere. Many marine animals, for example, are moving to the poles in search of a cooler climate (as reported by The Conversation).
