Depends what you mean by meditation. At a higher level meditation is
complete detachment from this plane and raising consciousness to a higher
level. That can only be done alone at a quiet time alone.

I used to meditate seriously but now I just sit and most of the time my mind
wanders. One of my cats always ends up in my lap. Cats like nothing more
than their pet human sitting still with an inviting lap!

But if you want to seriously meditate then dont do it in the same room as
your cat or any other person.

If you want to give positive energy you dont need meditation, just be nice
to your cat.

Positive energy is a mental not a spiritual quality. Energy is outwards to
the world, spirituality is a state of energyless calm within.
