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 Helping my cat My elderly, sick cat is extremely picky about food and is losing weight because of her diseases. While she will not eat an entire serving of this (or any other food) she does it a partial serving and she seems to be improving since we added it to her diet. She has gained weight and is perkier.

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 5 out of 5 by Great product for recovering cats After surgery my kitty wouldn't eat and I had to end up syringe feeding him. Most of your typical can foods, contain about 180 calories per can and you have to do many syringe feedings to effect a weight gain. Kitty gets tired of all the feedings and so do you. Then I found Iams Veterinary Max Calorie food. At 333 calories per can, you only have to do half the assisted feedings to get the calories of regular cat food. Even better my kitty liked the flavor, yours may too. August 12, 2016
Rated 4 out of 5 by Right product for specific situations Challenging to find a high calorie food for felines who are just light-weight, sr 4-paws, and picky. Consistency is runny, it appealed to 1 sr 4-paw when i topped another food w/this product. My very finicky guy was not impressed, but that could change, given his ever-changing taste preferences.

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 3 out of 5 by Product is good Website was easy and shipping was fast. But 5 cans were dented. They were in the middle of the case - so it appears that the cans were packaged dented rather than dented in shipping. This was almost 50% of the order. The box was not damaged at all. July 8, 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
Rated 3 out of 5 by Weird Texture! This dog food might work well, but my dogs hated the texture...it was almost like liquid. I ended up switching to another brand, Prescription, which I had used in the past. June 10, 2016
