My 12 year old cat began peeing places besides her litter box(usually on something on the floor) and chewing electrical cords when we moved into an apartment. She also will not go to the litter box if we put the cover on it now. She has never acted this way before. We have two cats the other seems fine and both are healthy. She has plenty of toys and her playmate. She also seems starving for attention even if we just petted and groomed her for an hour.
