I use Revolution on my cat monthly. The vet used to give me Revolution Blue...but this time I was given Revolution Purple. What is the difference between the two??

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Revolution for cats in the blue box is for cats weighing 5.1-15 lbs and the purple box is for cats under 5 lbs. I would read the weight range on the box to be sure you got the right one. Have a good night
