The flea & tick remedy works so well and does not make any of my dogs and cats ill. Being on auto ship takes the guess work out of remembering to order. Pausing the order in winter is so easy and you get to choose a start up month to get ready for spring. Customer service is the best. Treats i. Every box. My dogs look forward to those crunchy nuggets and the cat treats too, since my cats are picky. My only issue is the cat vials don't empty fast enough since they fight me. I wish they were similar to dog vials which empty fast. The cat vials sometimes have some left in it.
