Prevents and reverses urinary tract inflammation and subsequent crystals/stones
Excellent for my kittoh urinary issues - I have used it successfully to prevent cystitis flare ups and reverse partial blockages - when there is an active blockage I use Cystease alongside my Now brand pure D mannose powder and the Nature’s Answer brand corn silk drops as they are alcohol free. Using Cystease regularly has resulted in no further bladder stones or crystal issues. We never want to have a urinary tract blockage in this family ever again and I feel confident we won’t face any trouble as long as I keep my Cystease in stock. I was disappointed I can’t find it many places as I’m assuming it’s been discontinued in the United States. I’m very thankful sellers in other countries are keeping it listed on Amazon. I have never seen any side effects and as the capsule is easy to open and it mixes well into a Churu or similar treat, it’s easy to give to my food motivated bebes. When they’re not food motivated I just mix it into a tiny bit of a wet treat and wipe it on their front paws so they’ll wash it off. I love Cystease and I hope it’s always available.

Helps
If your cat has idiopathic cystitis this is the most important supplement for them. even more important than prescription foods. you can find larger bottles for much cheaper on other sites. my cat has improved drastically. i gave him 2x for one month now 1x as maintenance. he also has a prescription medicine which is important as well. but with Cystease his condition is much easier and less scary to manage! also get your cat off dry food.

Great for kitties with FIC!
My cat developed FIC a few months ago and has had a few scary flares since. I did some research on the best products alongside prescription food etc & came across an overwhelming amount of recommendations for Cytease. I give one capsule daily in my cat’s wet food with probiotics & dilute with water and I truly think there’s been a huge difference. So far he has not had a flare since being on this and I’m keeping my fingers crossed it stays that way. Anyone that deals with an FIC kitty knows how scary it can get during flares - I would HIGHLY recommend this product. I wish there were an option to buy it in bulk. It’s easy to pop open to dispense on food, and seems to have no side effects + is generally very safe for your cats to take. I asked my vet first before giving this however when doing so I was told by my vet it’s a great product!

The only thing that works
The only thing that has helped my cat with pain/inflammation. This had stopped his inappropriate urination after trying a billion different things. Stock up when it’s available!!

Effective but possibly causes soft stool - lowering the dose seems to do the trick
This definitely helped my male cat with idiopathic cystitis and crystals make normal-sized pees within a day. However, it seemed to give him very soft stools at the recommended maintenance dose of even just 1 capsule per day. I am now giving him 1/4 capsule twice a day mixed in a Churu treat, which seems to be effective without the GI upset. He is already on Hills C/D prescription food and gabapentin already, but had a few stress-induced flares recently.

Highly recommend for Feline Idiopathic Cystitis
My female cat has suffered from Feline Idiopathic Cystitis for 3 years. The urinalysis prescription food has prevent blockages and stones but unfortunately does not help reduce flare ups or general anxiety. We are on month four of using this and have noticed a significant improvement. She has not had a flare up. Normally anytime someone comes over to visit she will have a flare up and pee on all the rugs in the house but this has not happened while taking this. She also seems calmer in general. After reading reviews we decided to open the capsule and add the powder directly to her wet food once a day. I add a little bit of warm water to dissolve it and mix it in to where she can’t see it. My cat is picky so I went slow with this. She loves Churru’s so I added this to the food for the first week of adding cystease and then slowly tapered her off Churru. Now I just add it to the wet food with some warm water to dissolve and she doesn’t notice it at all.

Invaluable part of his routine
My 3 year old cat Miko was diagnosed with FIC this past year. He had his first blockage in December 2025. Once he came home I immediately took to the internet to find more information and I was so glad to have found a FB group that led me to finding this product, among other things. Miko is doing great and has been on this now for almost 7 months. Our whole lives have been changed with this illness but I attribute much of his success to this supplement. His diagnosis is stress induced and this product is the only thing that actually helps heal his bladder lining, which is affected by the stress. Vet gave med as well but that did nothing for actual healing from the damage, only help reduce stress/anxiety and pain.

Try this before meds
I don’t want to jinx it but even within 1 day I have seen a total shift in my cat. My vet gave me gabapentin and clomipramine. He always seemed zonked off the clomipramine and the gaba would make him have muscle spasms the day after I gave it to him. So far this just puts him back into his normal calm self. It’s only been a few days but hoping to see an improvement in his urinary behavior as well.

Parfait pour un chat fragile de la vessie et stressé
Mon chat de 14 ans a toujours eu des faiblesses au niveau de son système urinaire. Depuis un récent cambriolage pendant lequel il était présent, il est devenu plus stressé et se crée des cystites à répétition. J'ai tenté ce produit pour remplacer les médicaments vétérinaires très chers et je voulais quelque chose de plus doux pour son système digestif. Résultat, il ne se lèche plus à outrance le bas ventre (c'était si frénétique qu'il s'en arrachait les poils), ne souffre plus d'infection urinaire et en plus il est plus détendu. Je conseille !

Amazing product, Noticed a difference in my cat. 6 month intervals
These saved my cats urinary problem before it became a major issue. They say not a long term product, however I had my cat on them for 6 months straight no issues. Helped him pee easily, and more. Will have to re purchase a bottle, he's been out for a few months now.

Überzeugendes Produkt
Meine 12 jährige Katze aus dem Tierheim ist anfällig für stressbedingte idiopathische Cystitis ( ohne Bakterien,ohne Steine,ohne Kristalle im Urin ) Obwohl sie bereits über 2 Jahre bei mir lebt, empfindet sie selbst kleinste Veränderungen als Stress : Sturm, Gewitter, Staubsauger, Türklingel, Geräusche, ab und zu Besuch. Da meine Tierärztin keinen organischen Grund finden konnte, empfahl sie eine Cystease-Kur zur Stärkung der Blasenwand. Das Produkt ist sehr leicht anwendbar, die Kapseln lassen sich gut öffnen und das Pulver kann man unauffällig unter das Nassfutter mischen, es ist absolut geruchslos und wird deshalb vollständig gefressen. Ich bin von der Wirksamkeit des Produkts überzeugt, es können aber auch am Zusammenspiel mit folgenden geänderten Bedingungen liegen: Umstellung auf Schalen-Toiletten ohne Rand mit niedrigem Einstieg, 2 Toiletten mehr in der Wohnung an geschützten Plätzen verteilt, mit Krankenunterlagen darunter, wenn mal was danebengeht. Das alles konnte ich unauffällig in meiner 52qm Wohnung einrichten und seit 6 Wochen passieren keine Malheure mehr ( bzw. nur minimale, weil bei flachen Schalentoiletten ohne Rand mal ne Kleinigkeit über das Klo hinaus auf die "Moltex" geht)
