Rated 5 out of 5 by from prescription Science Diet Our cats require prescription food and I've been paying thru the nose at one of those pet big box stores. Chewy got me twice the amount for only 25% more than I paid for the smaller bag. Saving $33 a month. Wow, plus it's delivered right to my front door for free. Wish I knew about you two years ago.

Rated 5 out of 5 by from This product has been great for the cats' health and they really like it! We have long fed Hill's prescription diet to our four cats. And now we really appreciate being able shop for these products on line with your company, for both the quality of the products and the convenience of home delivery, rather than having to chase around looking for these products. It is difficult to find retail outlets that stock large enough bags to supply our four cats for a reasonable length of time, not to mention that the tiny bags are very expensive compared to the large bags. Thanks for being there when we need to order! Chewy.com has earned a 5 star rating with us.
