I have a 3 year old indoor female cat (half Russian Blue, half Persian)named Jezebel. In the past few months she has started this very passive aggressive behavior. She walks around the house "yowling" at me. She sits on the toilet seat while I am in the shower and LOUDLY meows, she will sit in the bedroom while I am in the living and howl on the bed until I come in there. She has started pooping on my bathmat, bed, etc. when she is not getting enough attention. She seems so disgruntled and unhappy! I cannot stand this! I took her to the vet a few months ago for a full checkup and nothing turned up so I don't think it is physical. I give her lost of attnention when I am home, but I work full time and travel about one weekend a month. I have 2 other indoor cats that she seems to love who keep her company. Anybody have any experiences like this?
