5 Healthy Cats We have raised 5 cats on Science diet. None have ever gotten sick. We have our Vet to thank for his recommendation 30 years ago. Our cats get only the Best, Science Diet. May 16, 2012
Great product for continued health. We have 2 cats that were ferrel, both had health issues when they appeared on our porch. We fed them Optimal Care from the time they chose us for care givers and there are no health issues now. Both are healthy and happy little members of our family. May 16, 2012
Healthy My cats have beautiful coats and are healthy. It is well worth the extra expense to know they are getting the nutrition they need. We try to eat a healthy diet so it is just as important for our pets to eat healthy. May 12, 2014
Adult 1 to 6yrs and Hair Ball Control Excellent food. I adopted my cat a little over a year ago. They feed the Science Diet so I continued but I added the Hair Ball Control because she is a Black Forest cat. OMG ! What a difference. Not only is her fur beautiful but she very rarely vomit's anymore. I have also noticed that she doesn't lose that much hair during one of our three times a day brushing. So, Thank You so much for the perfect food for my baby August 23, 2014
Optimum health w/ Optimal Care food! My cat officially turns 7 next week and has eaten Science Diet since day 1! It has always kept her coat beautiful, her size perfect, her attitude playful and active! She's never had 1 hairball, stomach or weight issue and I contribute that to the good quality of the Science Diet! I give her a few pieces of the oral care (she thinks they're treats) every other day to help keep her mouth healthy, and have started mixing in the new Ideal Balance with her regular food. She's loving it! Almost too active for me-I was expecting her to be a little lazier at 7! MissyCat and I are very thankful we found this brand so early on! May 17, 2012
Geno loves this food! My Geno enjoys optimal care dry cat food from Science Diet. His coat is so shinny and he is a very healthy energetic cat. August 1, 2014
science diet original dry cat food This is the only cat food my cat would eat, I try other cat food but my three cats stick their nose up in the air and walk away, so I went back to the store and i bought science diet original cat food, and I will not buy any other brand but that. plus if your cat won't eat it, you can take it back and get your money back.

Great food for my felines, and also rescue fosters! Science Diet has always been the food of choice for my own cats. My cats love both Optimal Care and canned tender chunks with gravy! Several years ago I started fostering for a local rescue group. While I initially tried less expensive food products, I quickly decided the fosters needed the quality of Science Diet! I have cared for moms with newborns, orphan kittens, and some with illness. So far, they have all loved and thrived on Science Diet! Without a doubt, I'll continue using Science Diet for both my cats, and fosters that come my way! February 6, 2014
