When I do rituals and circle castings, I do this in the guest room but this room is also the room where my cat stays and walks around (downstairs we have a dog and they don't go along). When I do the rituals with the door closed, she comes at the door and continues mewing...so I need to open the door because otherwise she distracts me too much.
I really like having my cat around me and I love her company but now I wonder if it is a bad thing for my magic? She is also black by the way lol. I don't see any other place where I am able to perform my magic...What consequenses does her presence have? Do you think it is a bad thing she keeps walking in and out the circle? What is your opinion/thought on this? Also what do you think about open doors and windows when performing rituals?
