For the sake of your cat, it is ok to say good bye - in fact, it is necessary!

Also - please get yourself a medical checkup. Obviously things with you and your kitty were fine for a while. Something else is going on, and you take it out on your cat, although I know you feel bad about it.

Please, please, get a checkup and an emotional health assessment. Any problem you have will not go away when the cat is gone...it will just turn into something else and you will still be unhappy.

If you cannot stand to put an ad on Craigslist, check with the Humane Society or even your vet for a no-kill cat shelter in your area.

Again, it is not only okay to say goodbye - it is ESSENTIAL. Reread your post and you will see why.

Please keep us posted.
