[morzh]

Well, I am an ethnic Jew of Soviet upbringing, non-religiuous and believing in God.
So, if the souls do exist (hope they do, though this cannot be a necessary consequence of existence of God), it is a bit haughty of humans to usurp the possession of souls; I think cats, dogs and all sentient beings have souls. Cats and dogs for sure.
When I die, I hope, other, of course, than my grandpa, my dad and whoever has died or will havedied to that moment, I will also meet there the dog of my childhood and my cats.
