Anergen is a hypoallergenic canine/feline diet formulated with immune stimulating technology and alternative protein sources to address food allergies/sensitivities. It is created by a veterinarian and owes its popularity solely to veterinary recommendation and word of mouth. For decades Anergen hypoallergenic dog food and cat food has been a remarkable alternative option for companion animals no longer able to tolerate conventional pet food protein sources and ingredients. This improved formulation is designed to take advantage of new processing methods to preserve natural value, and nutritional advances in epigenetics and nutrigenomics. Anergen is higher in protein and fat, and contains a comprehensive spectrum and higher levels of micronutrients/nutraceuticals including prebiotics, probiotics, enzymes, omega-3s, antioxidants and more. Small quantities of fruits and vegetables mimic what may be consumed in the viscera of prey, and contribute important vitamins, minerals, antioxidants and other nutrients.

Wysong Anergen Dry Dog & Cat Food is rated 3.4 out of 5 by 37.
Rated 2 out of 5 by from the food smelled like old plastic The 4 lb bag I received had 6 mos left before expiration meaning that it had been in the bag likely over a year. The food smelled very strongly of plastic. I poured the entire bag into a big bowl and let it air for several days turning it a few times a day. I will not order this food again.It obviously isn't moving off the shelf very quickly

Rated 5 out of 5 by from long-time buyer Our dog is 15 and has been on Anergen for most of his life. I was able to purchase it thru the Vet we were using, and I would buy it by the box. A couple times I was running out of it and went to the Vet but they were out or were closed that day. I started to get desperate, even drove 1 1/2 hrs to a pet store that happened to have 1 bag left. Then, MY vet stopped carrying it so I had to order it from Wysong direct, who would ship it to us with $75 order. What I'm trying to say is, that it is very hard to get. I now buy it from Chewy.com.

Rated 5 out of 5 by from Great wholesome food Like goldilocks, some foods caused poor stool, some caused horrible gas, now anargen is just right. Maggie looks forward to eating and licks her plate. Best part, even Murphy the cat loves it.

Rated 5 out of 5 by from Good alternative diet for cats with poultry allergies I have 2 cats who are allergic to poultry, and it is a challenge to find food for them without chicken or turkey in it, especially dry food. My one cat will eat canned food, and we can find enough variety for him. The newly diagnosed cat is a chicken and rice dry food junkie, and he was not wanting to eat either the vet prescription diets or the 2 poultry free dry diets I could find in my stores. I ordered several I found at Chewy, and this is the one he and even my non-allergic cats like the best. Its a good quality food, lamb is the first ingredient, and while it does contain rice and oat groats, it is otherwise grain free. The kibble size is small, so could even be used for kittens. If you suspect your cat is allergic to wheat, corn or any of the standard proteins used in most cat food, try this one.

Rated 1 out of 5 by from something has changed I have 3 cats - and have been feeding wysong for quite some time now. I have one cat with allergies - and thought this was perfect. They originally loved this food, until recently when ALL 3 stopped eating it. I don't know if the ingredients have changed, I have written the manufacturer - but have not gotten a response. My mothers dog has stopped eating it too. I haven't heard of any recalls - but something is different.

Rated 1 out of 5 by from cats didn't like it and got diareah from it Ordered this food for my three cats. Mix it up with their old food. At the begining, two of them ate it, although not very enthusiastically. One refuesd to eat her old food with even just a few of this kibbles mixed in. The two that will eat this food started to eat less and less. Note here one of them is a kitten who is hungry all the time. About a week later, I started to notice loose stool in the litter box. They could have diareah earlier, I just didn't notice I have stopped feeding them this food today, and would NOT recommend this product.

Rated 4 out of 5 by from Hunger strike finally broken! Just like everyone else who wrote a review, my cat has food allergies and just like most other cats, she REALLY was not into this dry food AT ALL for weeks (6 actually). We also feed her with Royal Canin Veterinary Diet Hypoallergenic Selected Protein PD In Gel Canned Cat Food, which is wet and that she likes very much so for the longest time, she was eating only the wet food. And then finally, when I was about ready to give up, she finally started eating it and is now eating as much as her previous dry food. Her bowels though are finally impeccable with the combination wet and dry, which was our goal in the fist place.
