Generally, the places where animals like to sleep are all places of geomantic omen.

This is not necessarily true! As the old saying goes, "the dog will live in the afterlife, and the cat will be poor"!

It's good to have as many places as you want. Not a place where cats like to go!

The habits of various animals are different. The environment that dogs like is basically good feng shui.

This depends on what animal it is! For example, mice that like to make holes and nests are not good in themselves.
