  • Quality food at a decent price! The many cats I feed are happy!
Size: 40 Pound (Pack of 1)
I have 2 indoor cats of my own but I also feed a lot of strays. I feel bad that I can't give them all the things and variety of food my indoor cats get so I'd at least like to give them decent food to eat. Diamond Maintenance looks to have much better ingredients than the stuff I had been feeding them from the local dollar store and is a better price per lb. Add in the fact that a 40 lb bag will last a good while and save trips, I decided to try it. From what I can tell the cats really enjoy it and are eating it up! I think I'll be sticking with this food going forward if the price stays around what it is now! ... show more

  • Excellent
Size: 40 Pound (Pack of 1)
I have 4 cats and was spending an amazing amount of money shopping for them at Petsmarts and Petcos locally. I wish I would have discovered this food earlier. This 40lb bag lasts us nearly 2 months! If you order it new from Amazon you don't even have to worry about the shipping, it's free (and for something that weighs 40lbs that's a good thing!) The ingredients aren't that great but at least it's not Corn or grains as the first ingredient..so it's passable. I mix the dry food with higher quality canned food to give them that extra boost of protein and flavor since my cats tend to get bored of the same food over and over. I find if I mix it with different flavors of canned food they NEVER get tired of it (it can even be a small can, nothing fancy if you can't afford the high quality stuff). The kibble is large in size but I actually prefer it that way..when the cats come in from a long day outside they are ravenous and the large size of the kibble helps them slow down and actually break it apart..I have never seen them throw up a hairball from this food like they used to from other dry foods and that is saying A LOT! I got so used to wet messes on the floor and now there are none! Add in the the wet food from time and time (not daily) and the kibble becomes easier to eat for them. It keeps their teeth very clean in it's pure form though. All in all I have ordered this bag 3 times now this year since I discovered it and it's saved me a lot of money and a lot of time and my cats are not overweight or lacking in any way. No allergies, shiny coats and full of energy..I simply can't find a reason to complain. ... show more

  • Good nutrition, lack of specific flavoring
Size: 40 Pound (Pack of 1)
The value for the money is great, and truthfully I was skeptical at first because of the lack of specific flavoring and the "maintenance" part, but my cats are fairly active and they LOVE this food. My cats aren't always particular on their food, however, they also used to do well with the recommended portions I gave them until this food, now they want in the bag constantly! I don't know if that's because it digests quickly or they love the flavor, but it's keeping them healthy and active and that's what's important. Personally I've seen that the flavor more comes into play when you have picky cats or cats that don't adjust very quickly to new foods. The ingredients aren't the best but they're definitely not the worst, and the nutrition is very well portioned out for moderately active cats that love to run around for a couple hours then pass out for another 14 in my opinion. Overall, I would recommend this for anyone looking for a healthy, affordable option for their somewhat active cats. ... show more

  • A Good Cat Food For What It Is - Feeding Feral or Barn Cats - Helping Them To Survive the Irresponsibility of Some Pet Owners.
Size: 40 Pound (Pack of 1)
This is a cat food of a category different from any other that I have ever purchased, used, or reviewed. This food does not contain the highest quality of ingredients, indeed there are many ingredients that you might prefer to omit from the diet of your pampered house kitty. However, this food has one tremendous, almost humanitarian advantage - it provides decent nutrition to the poor, abandoned, feral, and barn kitties that might otherwise have nothing much to eat at all. A friend of mine feeds enormous quantities of feral cats. She does this in a responsible manner, trapping the kitties to be neutered or spayed, with the younger kitties being rehomed by the local Humane Society. However, no matter how many she traps, no matter how many are rehomed, or sterilized, there are always too many poor little feral kitties - hungry, unkempt, and now facing the beginnings of another rough winter in New England. I purchase forty pounds of cat food per week, and she uses it to feed all of the wild, abandoned, and dumped kitties that inhabit the woods in our area. How people can just drive by, and throw their kitties out of the car, and then drive off again, I will never understand. But people do that, much, much too frequently to even be believed. With this decent.quality, and quite affordable cat food, many kitties will eat well and survive the winter. So, although I would not recommend this for a pampered house cat, I am grateful that Daimond is making it possible for so many poor kitties to make it through another rough winter. Until people learn to spay or neuter their pets, we will always be surrounded by the pathetic survivors of unwanted litters. If you can, use a humane trap and.catch those abandoned cats and dogs that you can, have then sterilized, and hope that a nice family will be found for them. Until the problem disappears, and I hold-out no great hopes for that occurring anytime soon, foods of this quality level are more than adequate for keeping a poor little kittie that never asked to be born and dumped, alive and fed throughout the winter. Support your local Humane Society, with their help, maybe this tragic situation of pet overpopulation can eventually be solved - in a kind, humane manner, and loving manner. Please spay or neuter your pets, and if at all possible - adopt a new fur-kid from your local shelter or Humane Society. ... show more

  • Great Brand! Cats Love it!
Size: 40 Pound (Pack of 1)
My Cats love this food, and I feed many. I've tried them all. This is a family own company which makes me feel better about it. 40 lb bag is definitely the way to go for our group of kitties at varying stages of life, including ferals. No colors to upset their tummy (it happens everytime I feed colored food.) ... show more
