Bella does the same thing! I'm afraid to leave her alone for 5 minutes. I've tried the bitter apple but if she's not using her mouth, she's using her nails

. She also does the same thing with the carpet and eating the carpet pieces. I've been covering the spot she likes but I would love to just make it stop. Any suggestion would help.
Also, I was told that if the paint has lead in it...it's normally a sweet taste and that's why they like the eating it.
