yes, I have done it- by the time I got the cat though, I had lived in this apt. for at least 6 months, paid rent on time, did not have parties or cause disturbances, did not ask for anything. At some point my landlord saw my cat, and did not do much because I was otherwise a 'model' tenant. There was one other time that I had a cat, and when I was asked about it, I said I was cat-sitting, and that seemed to work okay. I DID move though 6 months later when my lease was up.
