Cats are able to sense not only seismic activity, but also the death of their owner.
This was reported by the Zen channel "Main News. Sib.fm", citing zoologists.
There are two main versions of why cats sense the death of their owners.
According to the first, it is a matter of cat intuition. According to the second, cats are able to sense a specific smell that begins to emanate from a person's body several hours before death.
A cat, sensing the death of its owner, behaves extremely restlessly: runs around the house without stopping, meows loudly, and tries to get into hard-to-reach places.
You should not touch the cat at this moment under any circumstances; you need to let the animal calm down.
If your pet doesn't want to leave its shelter, try to lure it out of there using a cotton pad soaked in valerian.
For reference
A cat is a domestic animal, one of the most popular (along with a dog) “companion animals”.
