Easy transition to the Science Diet product. I was worried about the change of food. A waste of my time, Destiny is enjoying it and I totally trust Hills Health Science. We had a cat that required the Hills Health Science C/D version. It worked so well, that I bought the Adult version for Destiny. Now Cat and Mom are happy. A shout out to the scientists!!!!! Thank you!

Our little boy Cannoli loved Hill Science Diet Adult perfect weight food. He needed the help because he had a weight issue. He had lost 2 pounds and 5 ounces but still enjoyed eating this food. I will miss him meowing for his food especially because he knew that his bin contained Hill perfect weight food. Always in my heart

A Feline Culinary Love Affair Gone Wild

I don't know what sorcery Hill Science cooked up in their labs, but my cat is in love with this stuff. Her enthusiasm for this food is displayed by a swat to my face while sleeping, obliterating a thawing dinner on the counter, and voicing her opinions whenever I walk past her food bowl. It's honestly a bit unsettling to be yelled at by something that doesn't contribute to the rent. On Christmas, we decided to treat her to her beloved kibble. The excitement was too much for her, and she tore into the bag like a furry hurricane, devouring the contents with reckless abandon. Alas, her excitement led to an unfortunate bout of overeating, followed by a very un-festive cleanup. We decided it was time to stage an intervention and cut her off and have been giving her what we like to call "doo doo food" (brand name undisclosed). Miraculously, her behavior changed and the feline tyranny ceased. It begs the question: What on Earth is in this cat food?

Our big fluffy guy who has almost no teeth wasn’t eating consistently, was overweight, and had constipation issues. The vet suggested this as a more digestible food for him and it’s been AMAZING. He eats all of his food, is regular, and has lost almost 2 lbs! He’s getting around better and is generally feeling better. One bag lasted us 3 months, so it’s still pretty cost efficient too. We will definitely be sticking with this Science Diet.

Fillers and terrible ingredients

My cat Buster developed a terrible skin infection and double ear infection after eating this diet for 3 weeks. I took my time in gradually transitioning to this formula over 2 weeks and by the end of the 3rd week I found a horrible hot spot on his neck that he had scratched at and became terribly scabbed. It’s a shame that vets will recommend dry foods like this when they contain wheat gluten, brewers yeast/rice and other unnecessary fillers that pets, specifically cats do not need in their daily lives. Needless to say we no longer feed this dry food or any Hills brand for that matter.

Great Alternative!

I have been feeding both of my boys Hill's Science Diet since I got them as kittens. They've always liked the food, but have gotten a bit lazier as they've aged

I have been feeding both of my boys Hill's Science Diet since I got them as kittens. They've always liked the food, but have gotten a bit lazier as they've aged and put on some weight. I decided to try Adult Perfect Weight to see if they'd like it and hopefully give them a healthier alternative to lose a few lbs. They can be VERY picky so I didn't have high hopes. Shockingly, they seem to like it MORE than their current Adult 1-6 food I've been feeding them! I haven't noticed weight loss yet as it has only been about 2 weeks but I plan on putting them strictly on Perfect Weight now that I know they love it. Very happy with my purchase!!

Great solution for Tubbo-Tubbinelli!

If you ask Miss Purr-Cilla, she claims she is a Maine Coon....this is highly debatable (and not true)...she is however, a dizzy blond, prone to flabbiness and on occasion, after over indulging, has problems bending over to groom her particulars....since I clean out 5 litter boxes daily, I'm not thrilled to have THAT job also....so we started offering this food....A creature of habit, we have 2 bowls set up, the S D Perfect Weight is always on the left...and she goes to it consistently, and she loves it...and can now groom herself without any aide from me. Plus, some of the others will nibble on it also from time to time and seem to enjoy it also. Happy Mommy!

First bag was a hit, Second bag not so much

I have two senior kitties that need to lose weight. One is twice the others size so finding a way to balance their feeding fairly can be tricky. I usually feed them

I have two senior kitties that need to lose weight. One is twice the others size so finding a way to balance their feeding fairly can be tricky. I usually feed them a quarter can of wet food for breakfast, and again for lunch, then they have their kibble for all day feeding. The first bag of this kibble was great, my tiny cat lost the weight she needed and is at her perfect, healthy size. Our other cat still has a ways to go but he is definitely losing weight. I reordered the food and what I got looks more like dog food. The kibble is huge, and they no longer clear the plate of kibble like they used to (though they both still eat it). However, I am going to switch them to the back-up senior kibble blend I have until this issue gets resolved. My boy had dental issues when we adopted him and most of his chewing teeth are gone. This kibble is far too large for him. I have no idea why they think making the kibble so big for cat food would be a good idea.

Wanted to help my cat Mario loose weight, with out him feeling denied. So I went with Hill's diet, more expensive compared to others. 1 small scoop for breakfast, lunch and dinner. He seems to be adjusting so far. He lost 3 lbs. Vet did not want him to drop weight but gradually where he won't feel the effects, or punished . But where he could get more active as he looses. Arthritis and hurt knee doesn't help . And he seems to love this, so he doesn't know he is on a diet. I bought a 7 lb bag of fish, and a 7 lb bag of chicken. And alternate feedings, And we love our boy !
