My cat is 15 years old. She was lethargic and sleepy. My vet said she had the first stages of kidney disease and prescribed special food. I wanted to give her every chance possible so got for her. She seems to be playing more even though she does sleep a lot. But maybe that's just the way cats are at that age. I am encouraged by her playfulness and wanting to go outside to sunbathe

Lucky, is my 18 year old friend. He is declining in health and though I know I'll be losing him in the near future I have seen improvement since I've been giving him Blisso. He loves it, no problem there. And he is now eating, often. Before he just wouldn't eat, now thou I have to make extra trip to pet store to keep him in supplies. Why doesn't the vets in my area know about this product? It's a godsend. Thank you for helping my old friend feel a bit better.

My cat was so uncomfortable after treatment with antibiotics. Blisso turned her around in three days. We will never be without Blisso Advanced Probiotics.

I see a big difference with using this product, my cat seem not to throw up as much and they seem to like it. It has no taste difference in their food and it’s very easy to use!

This was purchased for my 12 yo cat who now deals with tummy and pooping issues. This has been a great help. Her appetite has improved and the projectile vomiting has stopped. The "accidents" have finally stopped almost completely. I was worried about her avoiding her food because of the drops, but she actually licks it off her soft food. Her vet approved.

My cat did not like the taste of BLISSO in her food. She would not eat any of it. I requested a refund.

the box of bottles arrived leaking, no buggy, cats started eating a dropper mixed in their wet food once a day, it’s quite thick and doesn’t fill the dropper very easily, have not noticed a change in bathroom habits, except no poop on the couch blankets, where one cat likes to do his business, he covers his pile with the blanket, so I am happy with that change, my last two cats died from kidney disease at age 10, so feeding my current two proactively is comforting. My first adult owned cat died at 18, but I adopted him at 5. The cats that passed at 10 were adopted as kittens and ate well from month 3, passing early surprised me, 1 was purebred Siamese, the other was rescued from our shelter to get a playmate for our boy who needed an older kitten to show him how to cat. He did not know how to squat to pee, stood and shot his wad backwards, bought a self enclosed litter robot to contain his mess, but it broke when I was hospitalized and the hubs didn’t realize he needed to empty the receptacle, that kitten was also a climber, but not smart he didn’t understand he was wider than 3inches and broke numerous Waterford glasses and a cake plate trying to walk on a high shelf behind the crystal, I kind of had an idea they were going to have health issues later, their teeth collected plaque and remedies to treat it failed, their first dentals resulted in 7 teeth being removed, vet said he’d remove one and the next came out too, those kittens I could handle. My current cats were rescues and Ferraro, I cannot groom them, or crate them to take to the vet, thinking of brushing their teeth is daunting, bliss o gives me some peace of mind that their guts are happy and they like their food, hoping it helps their longevity. It’s not adding stress.

I have three senior cats in various stages of kidney disease. I started giving them Blisso probiotics a few months ago. One cat has improved kidney values and the oldest one who is 19 has improved urination now . I would recommend this product for all cats .

So far so good !! All 3 cats seem to like your product. My calico kitty will have her repeat blood work the end of June. Hopefully her bloodwork will show improvement for her kidneys.

My Cat Won’t Even Touch It. He Smells It, Even After I Mix It Well In His Food. Then I Have To Throw His Food Away. I’ve Tried Several Times To Get Him To Take It, Same Results. I Just Threw My Money Away. I Really Had Hoped It Worked. Maybe On Some Cats, Sadly Not Mine.

It's too early to say whether or not there is improvement in her kidney values, but at least I can say she has no problem at all with it being added to her food. She seems to like the taste.

While the product is great, I ordered nine bottles and only received seven. They said they would send me the missing bottles, but I only received one and now nobody is returning my emails after a month. I don’t know if this happens to a lot of people or was I just the unfortunate one.

Both of my cats came to me with digestive issues; it was so bad the vet thought it was a very contageous parasite. The last vet saw the bloody diarrea was filled with undigested food! What a relief! I know now I've straightened their dgestive issues out for them! They now have normal stools, no blood & NO vomiting either!! We could not be happier!!!! Thank you Blisso

Our three cats were very picky. Sometimes they would love and other times stick their noses up. I keep trying though and they get Blisso mornings and Taurine at night. If I mix them together they won’t touch the food.

I was hoping this would stop my cats licking cause his skin itches. I think he is doing better but not 100% yet. have only used one bottle so far.

My cats do like it quite a lot. My cat with FELV and ulcerative stomatitis especially seems to enjoy it.. he's quite picky and very cautious but it goes a long way to see that the product does not bother his ulcers like many and most of other things.

this has helped my oldest cat with her diarrhea and other issues. She has even gained some weight.

I looked into Blisso Advanced Probiotics when our 10 yr old male rescue cat who never drank water no matter what kind of fountain, dish or water source I tried, had a sudden urinary emergency on a Saturday. He couldn't pee and completely out of character for him, he wouldn't eat either. The Urgent Care vet couldn't feel any major issues in the exam so suggested doing a subcutaneous water injection ("camelback") and an antibiotic with an anesthetic in case it was a UTI. It worked, but I didn't want to go thru that again, so searched for something to prevent it (other than a 5th fountain). Blisso sounded perfect, so ordered one bottle, adding it to his wet food daily. While the other benefits mentioned didn't pan out (he's still obsessed with food/constantly "hangry", and still has respiratory issues like snotty sneezing and wheezing), thankfully his kidneys, bladder and urinary tract are working great! And I even saw him drinking from the water fountain! The other cat (14 yr old female)always drank gallons and peed huge amounts, but with a very strong odor, so I started sprinkling a dropper of Blisso on her crunchy kibble (all she likes to eat), and she loved the flavor...we call it "bacon juice", and she always comes running for her "juiced-up crunchies". The odor of her pee seems a little milder now, so hopefully it's helping!

I was a little leary about ordering this product but it has helped my cat so much. He use to vomit everyday. Since using this product my cat has not vomited once! I highly recommend it if your cat is having this issue.

My 14 year old neutered old man was doing all the foul stuff ya'll described. Laying around ,no energy ,eating,liquid poops within 30 to 45 minutes . After 1 bottle of Blisso,he's starting show noticeable improvement in all aspects. He is playing again and his stool is improving. We'll be continuing Blisso

Not sure if Blisso is working or not , I messaged Blisso support and no one responded to my question so that’s a little aggravating.

I give it to 2 of my cats in their wet food and they take it and eat everything which is great because I have the pickiest cat ever if they don’t like it, they won’t touch it. They will starve so I’m glad that they are eating it and I’ve definitely noticed them drinking more and using the litter box more.

I have two older kitties 20 years & 17 years mother and daughter they were acting like they weren't feeling well, and now I see a difference. They are both acting better.
