But God told us (in Genesis) to go forth and multiply, and also " rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground." so TBF to the Lord, he was never intending animals to have ghosts was he?
Used to have one in our last house, we were there 15 years, regularly heard footsteps upstairs while we were downstairs, pictures/paintings of nudes being moved wonky on the walls, doors opening and closing. Never had a problem with it, got quite used to it. Now weve moved, no ghost.
