who and when invented the dog and cats nappies?

Dog and cat diapers were not invented by a single individual but rather evolved over time as pet care needs increased. The concept of pet diapers gained popularity in the late 20th century, particularly in the 1990s, as more pet owners sought solutions for incontinence, marking a shift in how pets were cared for. Various companies began producing disposable and washable pet diapers, catering to this growing market.
