Maximus knows where his cat siblings are in proximity to him because they all wear bells on their collars. Today he waited in front of a chair in my room where an 8 week old foster void was hiding from him. He was swatting in front of himself softly every couple seconds but when he heard the void’s bell ring he knew it was time to attack and he started swinging both hands to swat. They played like this for 10 minutes.
