I’m posting this blog a day earlier than usual because today is National Pet Day. Pets are a big part of American households. According the Humane Society there are 77 million dogs and 94 million cats living in American homes. Forty percent of households own dogs and about the same number own cats. The American Pet Products Manufacturers Association estimates that pet owners spend more than $47 billion a year on their pets and there is a huge market for pet-friendly home remodels.
