I have 2 cats with mid level Kidney Disease. According to the directions, once opened the bottle needs to be kept in the refrigerator which isn't a problem. The other requirement is that it must be given whole which is difficult because of the large size of the capsule and the stress of pilling a cat. So, I'm only able to give 1 capsule to them once a week with a pill popper when they get their fluids. Even so, I have noticed an improvement in the condition of their coats.

My youngest cat who is only 2.5 has started having some health issues so I've been looking into supportive care and supplements that may help him. I came across this Nephrodyl Synbiotic from Virbac. I checked with my vet before starting and she was comfortable with him using these. There are 60 capsules in the bottle; it looks like 10 pounds and under takes 1 daily and over 10 would take 2 daily. This bottle would last 30 and 60 days, respectively. This is a rather pricey supplement if you have a 10 pound plus pet.I was hoping I could sprinkle this on his food but the instructions state to give whole so I've been using the pill popper to get him to take it. I'm uncertain if I will continue as he has to take 2 pills daily already and I hate to add more on.There is no noticeable (to me) odor to the capsules.

I wish i could review these with more detail, but unfortunately my senior cat REFUSED to take these pills. I wish the capsules were smaller/more tightly packed because I feel they were large enough for her to easily spit out rather than passively swallow.

I have two male cats from the same litter that will be 8 this year. One had an SDMA value of 15 and the other had 14. Although they both still concentrate urine and drink plenty of water, I want to do everything I can to help protect their kidneys. This brand is well known so I decided to try it between vet visits. They tolerate it well, but I am a bit confused as to whether it can be sprinkled on food and if it needs to be refrigerated. I have seen conflicting information provided by the company online, so I am going by the bottle that says to refrigerate after opening and do not break or crush capsules. I did check with my pet insurance to see if this is covered, and I was told they don't cover supplements. At this time, I cannot justify the cost for two cats since I also pay for their insurance. I will finish the bottle since it appears to be high quality. I personally cannot afford it as a preventative and was hoping insurance would cover. If the vet ever recommends this supplement, I will find a way to buy it.

While my 14-year-old cat doesn’t have CKD yet (he does have end-stage HCM), his last blood test results showed that he’s borderline, so I’ve been managing his phosphorous intake in his food, much to his dismay. I’ve been giving him an aluminum hydroxide-based supplement, but, of course, I wanted to see if there’s a better alternative. Enter Virbac’s Nephrodyl Synbiotic capsules. The price is considerably more expensive than the other supplement I’ve been buying, and because my cat toggles between 10 to 11 pounds, he’s borderline on the dosage chart for either giving him 1 or 2 capsules per day. I chose the former so I can stretch the 60-pill bottle to a two months’ supply, otherwise the price would be even more out of my budget’s reach.I wish I read through the directions before getting the product, because the capsule must be administered whole, not opened or crushed. It doesn’t say with or without food, but I give it to my cat right before his meal. Because he has severe heart issues, he’s on a lot of meds and supplements, so having to give him another whole pill — and the ordeal/fuss behind it — is more stressful than beneficial. Also, he's become averse to hiding pills in his food or pill pockets. I also haven't seen any sort of difference or improvement since giving him these kidney support supplements over another brand.

This is a 60 capsule bottle of Nephrodyl Synbiotic Capsules with probiotics and prebiotics for dogs and cats, from Virbac. It arrived fresh and factory sealed. When I ordered these I thought it was okay to break open the capsules and sprinkle the powder over food, but the label instructions say not to do that, so I'm giving it to my kitty with a pill popper, which works fine. The capsules are small and I'd have to double check but I think they are actually between a size 4 and a size 5, which are the smallest two sizes (size 4 is commonly used for cats). I can't double check that right now because of the other thing that came as a surprise with these--they need to be refrigerated after opening. It's not a huge problem, but I do have to remember to grab a capsule of of the fridge when it's time. I'm not a vet so I can't tell if these are providing any kidney support, but either way I like that pro and pre biotics are good for the tummy, and I like that his is an excellent name brand. The only thing keeping these from being five stars is the absolutely crazy price, which makes it not a very good value, even if it does provide some kidney and digestive support.

I haven’t given my dog enough doses to truly tell if this is making a difference but I can tell you that the past 2 nights he has slept through the night without incidents & has not been begging to go out several times through the night like usual.I’ve heard among pet parents that this is a great product but often hard to find as sold out or on back order on pet sites.Grateful that I found it here and hopeful that it will help my sweet boyHe took it easy in a tiny piece of ham. It’s a tiny capsule that you need to keep refrigerated for maximum effectiveness. Bigger dogs like my sweet boy will take 1 in the morning and 1 at nightThe capsules are kind of pricey but most things that will help are so if it does, then I consider it worth it.Will order again if I see continued improvement.Also for those that will be seeking country of origin.. these are made in the United StatesI would order as soon as you know you need them as takes a bit to arrive.
