I use the plug in airfresheners too but mostly 'cause I like the smell. I use the relaxation fragrance. Our house is new and Murfee has been house trained for a long time and goes outside to do his business so I really don't worry about odors yet...at least downstairs. Upstairs is a different matter 'cause my daughter and 2 granddaughters live up there with their 2 cats. I just stay downstairs
