Drama: my unwanted pet.

Who needs me?

Yes, my dearest reader, I come to the point that my pet is unwanted, very unwanted as a matter of fact. How did it happen? Gradually, little by little my circumstances, my life has changed drastically from what it was, and now I have to make a very hard decision - to get rid of my pet or not. He became a source of my frustration, anger and god knows what else. Bad for me, bad for him and not good for the rest of my family.
  We adopted our cat from some shelter in a small town we were living at that time. He was a fully grown up cat. I did not know his background, his way of life before shelter and how long he stayed there but I am sure it was not cream and honey at all. By the way if you ever decide that you need a cat, please adopt one from shelter because it's a bad place for a cat. He needs freedom, ability to roam around and explore, not to sit in a cage. He is not a lizard or tarantula, he needs a lot of space to explore and to feel comfortable in it.
  Just, please, do not adopt a grown up pet, unless you are very gentle, patient with pets and people and other members in your family are the same - gentle and patient, because you'll need a lot of patience and love to give to an adopted animal. In my family it was not the case.
  We adopted our Homer(we gave him that name) to keep company to our another she-pet and from the very beginning she could not stand poor Homer. She hissed at him like a snake and tried to hit him and made sure he never came closer than a foot to her. She prevented him from eating his food whenever she could. She made him feel very unwelcome. It was just the beginning for poor Homer.
 He was outdoorsy type of a cat. At that time we were living in a big house in a small town where he could freely go outside and roam around our house and explore our big backyard. He was not stupid, he learned pretty fast his territory(our territory) and where his bread and butter was hidden(so to speak). He was not a quiet type of a cat, he was very vocal, but in a big house it was not a problem, and he was outside a lot, never mind weather (same as my children by the way).
  In ten years my children grew up, my husband lost his health and regretfully we lost our big old house and free roaming territory. We had to move to a big city to survive, with everybody crammed in a small apartment where you cannot go outside where and when you want to (at least if you are a cat).
 Since then Homer's companion (other cat) died from old age, people who paid attention to Homer moved. People who do not want to pay attention or do not have time for him are still there but... Who needs that 10 year old cat who meows all the time, who is bored to death sitting on the third floor of a small apartment without any escape to outside world?
  I understand, I pity him, but I do not have time for him and he understands that too, he is not stupid. He is extremely sensitive, and he cries, and cries, and cries... And he does not trust anybody, even me who feeds him. And I shout at him because I am tired and frustrated, because I work 7 days a week, because I leave house at 8am and come home at 8pm and I need rest. My poor unwanted unloved pet...

Where should I go?

 What can I do ? Shelter is not an option, they will keep him for a couple of days may be and then they will put him to sleep, because no one is going to adopt him. There are lots of cute little kittens without problems there. No one likes him at home. He is just an ordinary cat, black and white half-domestic scared cat  who annoys everybody. He just does not deserve to die and I feel responsible for him - he has been my pet for 10 years and  I cannot stand him most of the time. Such a drama....
