We have had our female cat since she was a kitten. She will be 2 in July. She has always been a great cat, never really any problems other than her occasional scratching of our couches or carpet. In the past i can think of 3, maybe 4 times she has peed on the floor or somewhere other than her litter box. Each of the times we ruled it as her being mad at us. (example, i was hospitalized for 4 days, and so she was basically left home alone for that time. when i returned from the hospital she had peed in the shower.)
But now she is doing it quite more frequently. In the last week she has done it 5 or 6 times. Every time she pees in one of the 2 bathrooms, on the rug in front of the toilet or sink. she is scratching up the rug, and pulling it apart as well. which makes me think she is just peeing and not "marking her territory" or something. we have yet to catch her in the act, we just find the eveidence later on.
Some things that might be helpful to you to know is that she was just spayed yesterday (and has peed on the carpet once today, but all other times was prior to her being spayed). We recently moved (the beginning of February) to a new construction home. So there have never been any other cats or pets in this home. and the rugs were purchased brand new after we moved in here. There are new people living in the home. My mother in law is living with us. the only other pets in the home are a hamster and a bird (the bird came into the home with my mother in law). The cat goes outside once in a great while (like when we go sit on the porch on warm days) but doesnt stay outside alone. And she is never around other cats.
Im not sure if any of that has to do with her behavior, or not, but i thought it might be useful. We are not sure what to do with the cat, and how to get her to stop. My mother in law is becoming quite irritated with the cats behavior (not that my husband and i enjoy it). but i dont know whats more irritating, the cat or the mother in law. thanks for any help!
