Cats are cute, but they’re also little wrecking crews in a home or yard thanks to their natural tendencies to scratch and mark territories. The domesticated ones have even found a home in neighborhoods while others continue to thrive in the wild. Despite their reputation for being dominant and independent, cats have effortlessly made their way into the hearts of many humans. Instead of expensive concoctions, make your own cat repellent to get the job done. Dogs and cats are interesting creatures, sometimes exhibiting strange behaviors that may leave you scratching your head.
