Sometimes your dog or cat doesn't eat as well as they should. There are many reasons for their lack of appetite, including surgery, illness, and stress. Your pet is most comfortable at home with you, so your veterinarian may suggest that you care for him at home as soon as his condition is stable; and may recommend that you feed a nutrient-dense diet to assure that he receives the proper nutrition as he recuperates.

Rated 5 out of 5 by Sad this is being discontinued! I just found this food and have been hand feeding it to my semi-anorexic cat. She will not eat it from her bowl. I think she finds it unappealing that way but she is happy to eat it small bits at a time off of a fork or spoon. January 9, 2017
Rated 3 out of 5 by Intermittent Feeding Only I've been using this for syringe feeding my dog through his PEG tube. Its perfect for that as its the right consistency to push easily. He's lost a lot of weight due to the illness and so I was using this pretty much exclusively the past few days because of the high cal content. Today, I decided I better make sure it had the "nutritionally complete" lingo that you look for on pet food cans. Ii does not. In very fine print you can hardly read, it says for intermittent feeding only (unless at the direction of your vet). Nowhere in this listing does it say that. So just be sure to use this as a caloric supplement added to nutritionally balanced dog/cat food. December 19, 2016
Rated 5 out of 5 by Excellent food for syringe feeding My 17 year old cat has been diagnosed with stage 2 of chronic kidney disease. A couple of months ago I bought a case of this food to use when she goes off her feed and doesn't eat. The consistency is like a watery paste. Just right for syringe feeding. Even tho Iams is perfect for assist feeding I still blend it because I also throw in a sprinkle of Epatikin, her b12 vitamin, fish oil, Dasaquin, pumpkin and occasionally some roast beef or chicken chunks or a little bit of salmon or tuna as needed just to get her attention. She growl talks and sucks at the syringe when I feed her. That's strange because she won't touch this mix if I put it in her bowl. Samirah's biggest issue was weight loss. She's gained two pounds while on the Iams. Highly recommended! November 6, 2016
Rated 5 out of 5 by So wonderful I immediately recommended to a friend Fast shipping and great packaging. I then recommended chewy.com to my best friend in Columbia SC and she is now ordering food and supplies for HER best friends from Chewy !! Thanks so much ! ACApplebee December 14, 2016
Rated 5 out of 5 by great supplement for orphans I have orphan puppies and this product has literally been a life saver. I started feeding in a syringe at two weeks at the doctors advice. Now at 3 weeks they eat it by themselves. They love the flavor the come running every time they see the can. November 3, 2016
Rated 5 out of 5 by Fantastic for syringe feeding. I have an extremely sick cat who developed acute liver issues while recovering from a tumor removal surgery. She also came down with a URI and ear infection, making it even more challenging to syringe feed her. Between her nausea, drooling, & stuffed up nose, it has been impossible to get enough calories into her to beat this thing. I ordered the Iams Veterinary Formula Maximum-Calorie Plus primarily because of the high calorie content. One can has 333 calories Vs. approximately 185 in a can of the Veterinary formula that we had been using. What I also discovered while syringe feeding this formula, is that the consistency appears to make it more difficult for her to spit out the food. Our first feeding with this formula went very quickly and was much less stressful for us both. I first fill a 2 ounce feeding syringe, then use that to fill individual 3 cc syringes for our feedings as my cat doesn't tolerate larger syringe tips. The somewhat grainy consistency did not cause any issues or clogs. I had one of my other cats do a little taste test and he enthusiastically consumed his sample. November 25, 2015
Rated 5 out of 5 by Excellent for my 17 year old cat to gain weight I was hesitant to try this cat food even though it offers over 300 calories per can. I also feed a cat food that has nothing but meat and vitamins, so this new food is much different with additional ingredients such as beet pulp. My cat NEEDS the additional calories as he has hyperthyroidism (controlled with methimazole) and the middle stages of chronic kidney disease. I am pleasantly surprised to see that he will eat it. I mix it in with his other food. It has been too early to see if he has gained weight yet. But the added calories I'm sure are a bonus. I add additional warmed water to his food--especially needed when I use the opened food from the refrigerator. It is worth a try to see if it will help your cat gain weight. July 13, 2016
Rated 1 out of 5 by Probably a great product if your pet can tolerate it I had high hopes for Iams MaxCal when I ordered it. I was trying to feed a very ill kitty who desperately needed calories. I was feeding her by syringe and though the food loaded into my syringes and came out fine without clogging (I only tried this once though), the extremely gritty texture of the food was too harsh for her and I didn't even try to feed it that way. I pureed the food for a long time, then put it through a strainer and it was still very gritty. She had some unknown issue with her throat and was having some difficulty swallowing already (she just acted like something similar to strep throat symptom-wise). She also just plain disliked it altogether. I'm not sure what the "grit" that I strained out was, but I left it overnight dumped into the empty can and when it was dried the next morning it was hardened and I couldn't even separate it back into the "small" bits. I didn't want anything like that in my sweetie's tummy. I think that it may have also upset her GI tract in the 2 days that I tried to feed it to her. If your pet can tolerate it, you can't beat MaxCal for calorie content though. April 14, 2014
