It is common for cat guardians to see their feline staring at the corner of a room, seemingly at nothing. We may try to look at their field of vision only to see nothing of note. There are even times when our cat is seemingly staring at us for a prolonged period, but their line of sight remains steadfast...
Spiders are a very extensive and diverse group of arthropods belonging to the class of arachnids. Spiders are related to scorpions, ticks, and mites, and only very distantly to insects, with which they should not be confused. They have four pairs of segmented legs and can regenerate a leg if they lose...

There are many types of vocalizations such as whining, growling and even howling, but barking is probably the sound we most...
As you know, the teeth of animals are specially adapted to the type of food they eat.

Dogs and cats are much more like us than we think, to the point that they are also ticklish.

Another reason is that the common names we give animals can be very confusing. A...
You may be aware that a dog can sense a woman's pregnancy.
