Maybe you should be put down because you have Bipolar and have problems with anger.

After reading this, I am sick. Your cat has had problems for years and you ignored it. Maybe there IS a medical problem. Behavioral problems can be fixed easier as soon as they are noticed. Cats can even be put on anti-anxiety medications.

And guess what?

If you can not afford to care for an animal, you SHOULD NOT have a pet. Proper care of a pet requires regular vet care and care when an animal maybe sick, physically or emotionally... instances like this.

Perhaps someone should yell at you and smack you across the face for being irresponsible and cruel.

Yes, you have mental illness, but that does NOT give you an excuse to neglect and abuse an animal.
Don't blame your neglect and abuse on your illness... MANY MANY people battle mental illness and do not smack a cat.

There is NO excuse for abuse.....

Now call an animal rescue group and be honest about your POOR treatment and care of the cat. Try to do something right by getting the cat into a home that is safe, loving, caring, and wants to provide the best.
