Only if we leave the seats up. If we leave them down, she eyes the sinks in the bathroom. (Needless to say, while I was home sick from work yesterday I mustered enough strength to clean the bathrooms. It was good for the sinuses.)
Don't know if this is normal behavior or not, but the seats will remain up for the time being. I keep thinking of Robert DeNiro in Meet The Parents and his training their cat to use the toilet. Wonder if it's catching and the other kitten will start to act human as well?
