Great Product for Challenging Pets With Illnesses! I have used the A/d formula many times in the past. I fed it to my cats who had cancer when they would not eat. I would feed it through a syringe and add water to give them an extra hydration boost. I am now feeding it to my 10 year American eskimo dog who has an autoimmune disorder. She can only open her mouth about 1 1/2 inches and it makes it very difficult for her to eat. But she LOVES the A/D formula and it is soft enough for her to eat comfortably and gives her the nutrition she needed right now. Thanks Hills for a great product!! June 16, 2013
picky eater likes taste My dog is recovering from illness and has had no appetite. I am able to feed him using a syringe. He has always been a picky eater and seems to like the taste. The calorie content was not listed on the sample can the vet gave me so I was investigating this online. I was so excited to see your feeding guide. Thanks, Hills. December 11, 2012
This Product was a life saver for my cat We have been feeding this to my cat. We fed this food to him by hand. We placed it in his mouth. He has gained almost an entire pound in a week and is up and around again. He ate some food on his own today. Hill's is awesome. My cat is my best friend and it means the world to me to see him gaining and being ok again. Thanks Hills!!! November 24, 2012
Product does what it is supposed to do for my dogs digestive system my dog has been on your product for 5months. So far all his blood values are where they are supposed to be so the diet is working. However my dog does not like the smell or taste and I have to doctor his portion with vegetables and occasionally boiled chicken sprinkled on the top to get him to eat it. I am very thankful that his levels are holding steady. I do not like the fact that the cans always have big air bubbles in them instead of being full. My other concern is the cost of your may be ok for short term but at a can to a can and a quarter a day forever in my dogs case is a real hardship for me on a retired fixed income April 11, 2014
The best for a sick cat We started buying this when we had a very sick cat. This cat food really helped him survive even when it looked like he might not make it. The A/D is good for force feeding your cat when he can't eat on his own. This was the only cat food we could use that he could keep down. This was instrumental in his recovery. April 8, 2014
A-1 My dog loves this food. Very healthy. Solved all the problems we were having with other foods. March 8, 2014
Wonderful food for recovering kitty We still aren't sure what made my kitty's weight drop from 13 lbs to 7 lbs, but he was not in good health. Since he refused to eat or drink anything on his own, the vet recommended 'assisted feeding' with this brand of cat food along with some prescription pills and fluid injections. The food mixes well with water and can be fed via plastic feeding syringe. After two or three days of syringe feeding, my kitty is eating this food right out of the can. He seems like he enjoys it and he looks a lot healthier. Thanks for making a reasonably priced prescription food that my kitty enjoys eating. February 26, 2014
Made my cat well My cat recently became very sick. She was not eating or drinking. Took her to my regular Vet , they did a bunch of tests found nothing wrong . Gave her IVs and force feedings,nothing helped. Took her to another Vet who noticed a red sore throat. Gave me medicine and A/D to give her mixed with water given with syringe. Made her well ,and now the is all she eats. Saved her life! February 16, 2014
