Cleaning to remove pet odors and stains from your home can seem like a never-ending task, especially if you have a naughty pooch or kitty intent on soiling the curtains, carpets, or furniture in your home. For some pets this is just a bad habit but it can also be a symptom of a deeper problem in your pet. Before tackling the cleaning issue, make sure your pet isn’t stressed, depressed or otherwise unhappy for some reason.
