Pawalla is a subscription box service for pets.  Each month a new box is sent out to your pet with lots of great goodies in it selected especially for them based on their profile.  Their profile is made by you when you sign up with their age, size, etc so they aren't sending puppy food to a senior dog.  I love that it was customized to my dogs.  Make sure you check out my Full Review. to see what the pups got and how awesome these boxes really are.  You can even get them for cats!
