My cat Lily 6 years old. I got her fron the shelter she was adopted as a kitten but tajen back to the shelter at the age of one year old. That should have given me a clue but I felt sorry for her. She promptly broke two glass birds kilked two of my betta fishes(I have no idea how but I found them dead on the floor. Likes to chew wires. Chewed up two of my charging cable dor my phone. She is a talker meows all the time especially at night. Used to sleep with ne, not so much lately when she did she bit my hand so hard that she drew blood.She decided after 5 years with me that she wants to go out but I prefer not to because I have an outdoor cat who lives in the backyard and I don't want Lily to bother her because Lily is very big and intimidating. Now she is constantly at the door wanting to go to the backyard. I got her used to having a leash, so I can controll her. Otherwise she runs after all animals like lizards birds etc since I also have a birdfeeder. My question is how could I train her to a quieter more peaceful cat. I love her but she can be very annoying sometimes Thank you
