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

Important supplement
My senior dog has a number of medical issues, including liver, heart, kidney and dental disease. His diet is severely restricted because of these, and he was steadily losing weight. He could no longer eat kibble, and had no interest in the special or prescription diets suggested by his vets. I added small amouts of the gel on his food, and he gradually became more interested in eating. He's slowly regaining weight and acts as though he's feeling better. The gel looks like and has the consistency of brown gravy, smells like bacon, is ready for use, and does not require refrigeration. The bag has a handle and a resealable cap, so it is very convenient to use. It is rather expensive, but it is the only thing I've found to improve my dog's metabolic status.

Dogs love the taste
My dogs are very picky eaters. I was spending way too much money trying to find a food all 3 would eat that gave them what they needed and throwing most of away when 1 or all refused or got sick. When one of my girls had a litter, she was struggling to keep weight on then randomly stopped producing milk. I needed something to get my girl feeling good again. It’s only been a few days but she is already feeling better and producing milk. This has been amazing.

Works great!
I started giving this to my 16 year old cat for gaining weight and help with her diagnosed diabetes melitus and possible kidney issues. I increased her hydration with bone broth and added the weight gainer as well I shook the bag as instructed and gave her a teensy bit once a day. The result have been huge. I had no idea it had an appetite stimulantant and it does show! She ate it all up with the Weruva low phosphorus canned food. I did notice too she feels a little heavier and is very well hydrated and active like a kitten again! So far so good 👍!
