Sandie and Mary, thanks for your advice. Sandie how many cats do you have now, and how many litter boxes?
I am pretty sure which of my cats are the offenders. Squeakers has been treated for UTI but may need more antibiotics, his sister Emmy Lou is just a rotten little girl, she's the one who is peeing in corners behind furniture. Hopefully once I find homes for my fosters the peeing problem will resolve itself. I just get so frustrated, it seems like all I do here is scoop and snoop! I do love each one of these little fur balls with all my heart and am happy to have them in my life. I just don't want to be ashamed to have family and friends visit. Also, do any of you use any kind of air purifiers?
