Bought last week and tested for a new cat! A Duch resounding success: A purring cat had to comb from the head to the tail, and then even offered me the other side of the body for combing :-) (Depends certainly from the animal from or my former cats need a short "settling in period".)
I know that part really just for grooming (ie not just a one-off lice investigation).
Conclusion: For cats Highly Recommended!
