Many cats have a strange habit of staring at a blank wall while sitting in a loaf position.
This behavior does not always mean that the cat is offended.
We'll tell you in what other cases cats do this.
Most often, cats do this when they are cold, but this is not the only explanation.
This behavior may indicate that your pet is very tired or sick.
If the cat does not just look at the wall, but directly bumps into it, this is a cause for concern and you should contact a veterinarian.
