Seems Good!
Sadly when I bought this because my cat was losing weight, his health was already out of control and he didn't make it long enough for the paste to arrive. So it sat in the fridge in hopes it would still be fresh when needed. We recently were sort of forced to adopt a cat who got run over in front of our house. He has a pelvis fracture, vet said 15K to do surgery which we couldn't do even for one of our own beloved cats, BUT, the vet said cage rest for 2-4mo usually works ok (the advantage of surgery is they recover faster and have less chance of a limp) so that's what this little guy is doing, just lying in a dog crate on pee pads, getting pain meds and waiting for his bones to knit. We've had a lot of little milestones along the way but a biggie was eating. He had a couple licks of food once, but otherwise fasted for an entire WEEK after his injury, and I was getting pretty nervous so I broke out this paste. I hesitated so long because wrestling a sore animal to get stuff crammed down their gullet seems like it would risk aggravating the injury. But he didn't fight! Apparently it's not tasty enough for him to eat it voluntarily (I did try first, plain on a plate and also mixed with hot water to make a broth) but when I shoot it in with an oral syringe he doesn't hate it enough to fuss! Smells like bacon to me. Not only was it a great tool while he was refusing food, to help prevent starvation or malnutrition, I think it actually woke his digestive system up, because the day after we started this (2.5mL or half a teaspoon, every 12h) he finally started accepting meals! YAHOO! I am continuing the paste though, figuring he needs the extra nutrition, and since it's open I may as well use it up. Some tips for doing oral syringes: I like to kneel behind the cat so they can't back up without hitting my thighs, and I bend forward over them til I can see their face, thus pinning their body down somewhat with my chest and restraining side movement with my elbows. With one hand squeeze the corners of the mouth, or in other words the jaw hinge, and the mouth pops right open. With the other hand shoot the liquid in, aiming at a slight angle so it hits the inside of the cheek, do not aim centrally or it can go down their windpipe! And only shoot in maybe 1mL at a time, let them swallow and have a couple breaths, then do another bit. If they feel overwhelmed by too big a mouthful, like they're being waterboarded, of course they will develop a fear of the procedure and become difficult. I'd also suggest if you have a very sore cat like ours, and you're not experienced with oral syringes, practise with just some water, on one of your healthy cats, so as to not be manhandling the one with broken bones or incisions or whatnot. I find that being graceful and fast gets it over with in a split second, before they have a chance to get upset. But it takes practice to get graceful and fast. While you're in the stage where you're not great at it yet and it's a bad time, remember to try to bring calm energy to the situation. No matter how frustrating it is or how badly they scratch, acting upset will only make the task harder, so breathe deeply and don't tense up, murmur cheerfully no matter what! Channel your inner Mary Poppins or Mr Rogers LOL. But maybe you'll be lucky and your pet will eat this voluntarily! The texture and smell are VERY nice compared to most pet supplements I've tried.

This stuff is awesome
I used this for a few puppies, it's amazing, perked them right up, and are gaining weight, and eating great! Then I gave it to a fussy female I have, and she is doing awesome. I think this is a great product, and mine love the taste, they luck it right off a plate. Now, people that have purchased this and gave it a bad review, because you didn't like the smell, or your dog doesn't like it, please scroll by, and don't give something that could be useful to someone else a bad review. I think this is a must for all breeders...

Something seems different with the latest batch and not in a good way
The new pouch, with the picture of a cat & dog on the label, rather than the old purple and white, seems to have changed. I have been using this stuff for years, since the old purple and white plastic cylinder containers, and it had been working well. When I got the new two pouches, in my latest subscribe and save order, they seemed almost balloon like, which I just figured that they had been filled under pressure, initially. I opened one, it smelled okay, and I used it as I have been using it. One of my cats is 16 and has CUPS (mouth sores), so she gets fed meat babyhood mixed with other things like broth and a tablespoon of this to give her more calories. She had been doing fine, and has been eating the same mixture including this for over a year. When I made her breakfast a few days ago, with this new pouch, she immediately threw up after eating. I figured it was just a thing, so I gave her some saved in the fridge in an older batch, using the older Miracle Vet (chilling them works better for her sometimes) and she ate that fine. Later, I tried the newly mixed batch, with this new Miracle Vet again. Again, immediate and violent vomiting. I waited a few days (not adding the mircale vet to the mix, and she ate just fine). Then I tried some with the new Miracle Vet added and she immediately threw up again. I need to see about a refund on these, as either they have changed something, or they are contaminated somehow. I wondered about the balloon-like inflation of the pouches and now I'm wondering if it may be due to bacterial biological activity and resulting gasses (as I said, it did smell normal when I opened it). I am very disappointed as this worked so well for so long, I went through dozens of containers of Miracle Vet over the past few years, and now I need to see about returns (it costs too much not to) and find an alternative additive to give her more calories. Anyway, I'll be curious to see if anyone else reports problems with this latest batch in the new pouches. I should sit down and compare the ingredients, since I still have an old MV cylinder around (but not a purple and white pouch, unfortunately I threw my last one out when it was empty). I made check the local Petsmart or Petco to see if they have any older pouches of MV.

Does what it’s supposed to do so far.
I never write reviews but this product has changed my dogs life in the span of one day. My 15 year old dog tore his ACL and was not a surgery candidate. I was told we would have to let it heal on its own. For the last 2 and a half weeks he has been so picky eating and very low energy, probably because he isn’t getting enough nutrients. I bought this yesterday and gave it to him mixed with some food. I was so surprised he ate all his food then a few hours later he was up and walking around more. To my surprise he walked over to his food bowl to eat more, this was the first time in weeks he walked to his bowl and didn’t wait in his bed for me to bring him his food. This morning he ate again and seems to have more energy even stared wagging his tail again. I know he is still recovering but this product seems to have stimulated his appetite like advertised. I only gave it 4 stars because he has only taken this one day so far, but it has really helped him and gave me hope that he will go back to being himself again.

Highly recommend
After my foster cats and resident cats became sick with giardia—likely picked up from an adoption event—I was introduced to this product by a cat rescue. Here’s how it helped and what I learned: How This Product Helped: Encouraged Nutrient Intake: When my cats lost their appetites due to vomiting and diarrhea, I mixed a small amount of Miracle Vet with warm homemade broth. This helped them get some nutrients without overwhelming their digestive system. Tasty & Easy to Administer: My cats enjoyed the taste, making it easy to drizzle over wet food or mix into broth. Eventually, they would lick it straight from a plate. Great for Recovery & Post-Surgery Support: I would recommend this product for pets recovering from spay/neuter surgery or illness when they need extra calories. Long Shelf Life & Storage: I stored it in the fridge after opening and plan to freeze it to extend its shelf life. Important Things I Learned About Giardia Treatment & Prevention: Hygiene is Crucial: Giardia can persist on a cat’s fur unless they are bathed and their anus is cleaned after each bowel movement. I used chlorhexidine soap and wipes regularly. Bathing & Cleaning Routine: I bathed my cats at the start and end of their medication treatment using chlorhexidine shampoo to remove any lingering giardia cysts. Between baths, I wiped their fur and anus frequently, especially after bowel movements. Litter Box Maintenance: I thoroughly cleaned the litter box after every bowel movement and did a deep clean every other day using a recommended bleach-to-water mixture. I also dumped all the litter and replaced it with fresh litter every two days to prevent reinfection. It was a lot of work, but I did not want this to come back. Cleaning Protocols Matter: I bought a steam mop for disinfecting floors and carpets and learned that while RESCUE cleaner is effective against many pathogens, it does not kill giardia cysts. This may be why my fosters picked it up at the event. Isolation & Deep Cleaning: I washed all bedding in hot water and bleach, tossed non-washable toys, and thoroughly steamed the cat condo. Probiotics for Gut Health: I added FERA probiotics to the broth mixture with the appetite enhancer to help support their recovery. Cautionary Notes: Do Not Give This to a Vomiting Animal: I was specifically advised not to give this product if the animal is vomiting, as they may be unable to hold food down. Instead, I used homemade bone broth with slippery elm powder to coat and soothe the digestive tract. Proper Syringe Feeding Technique: If necessary, I was advised to syringe-feed the slippery elm mixture by placing the syringe between the gums and cheek—not directly down the throat—to prevent aspiration pneumonia. Final Thoughts: Giardia was a nightmare, but I now understand treatment and prevention much better. I highly recommend this product for pet owners, rescues, fosters, and shelters as a valuable tool for recovery and weight gain—just be sure to use it at the right time in the healing process

I preferred the previous packaging item
I used this product for years on my Shepherd Pittbull mix who had a hard time gaining weight in his final years. He had heartworms since he was a puppy and was on medication his entire life that left him looking thin and malnourished. This item kept him looking great and feeling great. You could tell he was so much healthier and his overall demeanor was happier and more energetic. He did later on pass from old age, but I reordered this for a foster dog who was looking thin. She didn't like the smell, and I would have to mix this with other food items to get her to eat it. It did not seem to work as well this time around. The smell was notably worse than the previous bags I had ordered but didn't smell spoiled. It also looked as it should. The bag is a large size so I would say it was worth the dollars but I wish I could say I got the same results this time around.

A godsend
Let me tell you this high calorie weight gain food for our cat has been a godsend. He is 17 years old and he recently had pneumonia and wouldn't eat. I was able to syringe feed him this twice a day long with some of his regular wet food and it really helped him to heal faster and not get hypoglycemic. It's really easy to use cuz it is very thin compared to some of the other ones that I feud on amazon. It did not cause him to have diarrhea at all and maybe even helped him heal a little bit faster because he didn't lose weight.

Picky Pup doesn’t hate it.
My 13 YO Yorkie basically stopped eating. He only weighed 9 to begin with, and dropped 2, down to 7. He was slowly starving himself to death. Took him to the Vet, borderline kidney failure, so got him on meds but still having problems getting him to eat so through research I found this product. I was hesitant because of some one-star reviews. Decided to give it a try anyway as he needed the calories and nutrients. It arrived a day earlier than estimated, was in good shape, and packaged fine. No broken carton, no spillage. The top under the cap had a safety seal on it. I shook and gently messaged the bag to make sure all was mixed, then popped the top. It looks like thin oily peanut butter. It also has a similar taste (yes, I tried it). My little feller will eat pumpkin, and peanut butter, so I put some on a teaspoon and he licked it right down. I have high hopes this will help put some meat back on his bones but this is the first day (01/10/25) so hard to tell at this point. So far so good, and it certainly can’t hurt to get those extra nutrients in him. Good luck and god speed to all. Update 01/13/25: I know it’s early, but wanted everyone to know he’s gained a pound in 3 days. He is back to eating his “Loaf” brand dog food. Still mixing in the Miracle Vet. Also, from the Veterinarian visit, I picked up a product (prescription only) called Entyce that supposedly enhances/stimulates appetite. Whatever, he’s gaining weight, has his appetite back, and I’m a Happy Camper. Update 06/18/25: My little feller has gained his weight back and is eating normally. I am no longer using the Miracle Vet as he is eating just fine. I have been mixing a couple of tablespoons of Beef Broth into his Loaf, which he seems to like. Hard to tell cuz I don’t speak Yorky and he doesn’t speak English. Anyway, I am going to credit Miracle Vet with getting him on the road to recovery.
