Take a deep breath- the short answer to this question is NO. Thankfully (sort of) our furry friends cannot catch lice because it is only a human parasite. Human Head Lice cannot live on non-human hosts. Now, while lice is a major wrench in your day, our clients are so thankful to find out that their cats and dogs are safe from an infestation. Rest assured, you do not have to worry about your pets! PHEW =)
