I don't know what to do. A cat expert told me that the most humane thing to do would be to put my cat down. I have had her for 6 years and I don't want to do that. She has always been kind of aggressive. Always bit and scratched with intention to harm. It is weird because she can be very sweet. She sleeps on my chest sometimes and headbutt my face while putting ferrociously. She hurts me about twice a month now. I think I know some of the triggers now. I have to keep her in my room most of the time because I live with a room mate who has 2 cats and who my cat attacks if she sees them. I let her out when I can supervise. If she sits meowing at the door for too long and I don't let her out, she runs up to me and bites the **** out of me. It hurts and I bleed. She won stop biting my unless I use force against her and j hate doing it and I feel really bad but when you are in that moment it us really hard not to because you are in shear panic aND are just trying to get her off whiles she is brutally gnawing and clawing and making these horrible noises. I have tried a spray bottle and loud noises but they don't seem to work. Why is she biting the hand that feeds? I love and care for her but she gets so angry...like a spoiled little child. If she doesn't get what she wants she throws a temper tantrum...but her temper tantrums are aggressive and dangerous. She Has Even Bitten My neck once while in the middle of yoga (it wasnt as bad as usual, but still its pretty bad when she reaches that level). Does anyone know what behavioral interventions I can use to get her to stop being so angry and agressive?
