Reddit reviews Starting from Scratch: How to Correct Behavior Problems in Your Adult Cat

Make sure she's getting played with enough; she could just be bored. Cats are just like you in that they need plenty of mental stimulation. Unlike you, their whole world is your house so it's important to give them plenty of enrichment! My girl, Pixie, used to spend hours after we'd gone to bed pawing at thibgs and crying. We finally learned that she needs about 20 minutes of play leading up toward bedtime.

Cats most enjoy play that mimics a real life hunt, so I've always had success with Da Bird. When you swing it lightly over your head, it gently flutters like birds wings and cats go crazy for it.

You're right about reinforcing her behavior by responding to it at all. Positive or negative, any response reinforces her actions. You really need to grit your teeth through it all - No talking, no looking, no tossing things at her in frustration :D

I've recommended this book several times in the past because it really helped me a lot in understanding my cats' behavior and responding appropriately. It's an easy read and can be thumbed through just to check a relevant section.

Edit: If you adopted from a center, check with them to see if she seems friendly with other cats before bringing another into the mix. There are ways to provide enrichment without potentially compounding the problem. Just because she had kittens doesn't mean she'd automatically be open to a new "friend." Ask me how I know!
