Thank you for the quick reply. I really am a bit desperate.
I can't hide him because the super knows and he's terribly mean, he calls my landlord to complain about me for things I didn't do, like wearing high heels in the apt. (I don't even own shoes, only tennis shoes and slippers), imagine if I had a cat...
I have to put up more notices and web ads, yes. I haven't put up enough. But no one has reported him as lost either in the neighborhood or the websites. I've registered at vets around the area, the major animals organizations, etc.
I'm thinking of asking the landlord if he can let the cat stay until I can find the owner or someone to adopt it. But I'm afraid he'll say no and I'll have to dump him in the street. Right now the cat's sleeping next to me, he only wants to be on my knee all the time. He's beautiful and so dependent on people!!! He never uses his teeth or claws, he's so well behaved. And he's used to being held in the same position as a baby to sleep.
My father is very sick in hospital and I have no one else in the world. I really want this cat. But finding another place to live and moving on such short notice is impossible, what with having to work all day and be with my father in the hospital the rest of the time.
