Males have two colours, females have three. My last cat, Maggie, was exceptionally smart and "listened well" to commands at an early age. Of course, I like to take credit for that because I spent a lot of time teaching her. Use to come to me on command, follow me aboust, fetch thrown balls of paper, etc. P****d off the ex to no end. She took her when she left. In answer to the next question, does it matter ?
