Excellent Product
If you have a cat you know that change is hard. Sometimes moving a chair from one side of the room to another will cause a cat enough stress to cause a sterile cystitis flair. Well, I found a puppy at a gas station and brought him home. My poor old man cat went into panic mode and started peeing outside of the box. Since I work in a vet's office, I tend to bring home the unwanted or unloved animals on a regular basis and had never had this problem before, I figured it had to be just a UTI, easy peasy. It was not just a UTI. It was weeks of testing and changing litters and medication. But nothing helped. After some research, I bought this along with L-theanine and BINGO! no more peeing outside if the box. The L-theanine calmed his frayed kitty nerves and the Cystease took down the inflammation in his stressed out little bladder. We did once daily treatment for 2 months and now that the new has worn off the puppy we were able to stop all of the medications completely. Excellent product!

Holy Grail?
I have a cat named Christopher, aka Pisstopher, who has had urinary issues since I took him in as a stray a year ago. I’ve spent over $4,000 on him for emergency vet visits, to get PU surgery, and even to get his new urethra widened after PU surgery to the size of a catheter. He’s been on the prescription diet but still struggles and I can’t figure out why. We started doing wet food only to help but that’s not economical or possible if I have to be gone overnight at any point. Plus, he was still growling and licking after eating. I got a supplement to mix into his wet food in hopes it would make eating dry food better for him (he prefers dry food anyways), and within a week he was clogged and in extreme discomfort. I had just gotten these supplements in the mail that day so I immediately opened and mixed one at a time in a little water and syringe fed two to him. For about 30-45 minutes after getting the pills he kept pushing really hard but I almost immediately noticed he was able to get small amounts out which was better than before. After about half an hour he laid down and slept for a few hours, so the calming effect works! I woke up extra early to rush him to his vet and right as I got to the bottom of the stairs I almost stepped in a puddle of urine. I’m not sure if the crystal was passed because usually I see a little blood when that happens but still, it allowed him to urinate and lower his risk for a bladder rupture. He is acting happy and bright again :)) I really hope this helps get rid of these issues forever, I hate to see him always going through this.

Works so well!
One of my kitties FIC and flares up with stress. It was recommended by someone in a FB group to use this. I used this twice daily, along with Cornsilk, Theanine and Tryptophan to calm everything and once he started peeing normal, went to a maintenance dose of one capsule daily, as well as tryptophan and Theanine. Worked so well and saved me an another expensive vet visit. He’s a happy boy now!

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.

My cat was diagnosed with FLUTD, this has been a blessing!
My Charlie was diagnosed with FLUTD Nov. 2024. Ever since he had averaged an attack every other month since. He is on Hills Perscription C/ D uniary stress dry food. He will not eat the can stuff. I started giving Charlie the Feliway Cystease in the beginning of last month August 2025. He gets one capsule every morning and since I started this he has not had one attack. Charlie's FLUTD is triggered by stress and Cystease has an ingredient that acts like tryptophan which I believe is what keeps Charlie from stressed. Either way, it seems to be doing the trick!!

CYSTEASE for CATS UTI
Amazon always delivers so fast. It seems they always understand the urgency for my poor CKD cat. He's miserable with a UTI. 2ND day on Cystease and it's helping already. I have heard i can use it a maintenance dose so this doesn't happen again.

Great Cystitis/Urinary Health Supplement Option!
My Abigail was diagnosed with Cystitis last year after multiple bouts of inappropriate urination. Aside from changing her diet, I read a lot about Cystease and its ingredients. Feliway is a brand already trusted in my home as we use the diffusers so when I found out they made it made me feel more at ease. They have a very mild taste (yes, I tasted it!) that she doesn’t turn her nose up at. Usually I mix it in a little Churu and she gobbles it up. It’s been several months now and there have only been two incidents - which I think were out of spite because you know, cats… She also seems happier and more social with her siblings. As always, I would always recommend consulting with your vet prior to introducing something new into your pets diet.

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.

Great product. Please return this product to the market! My cat loves it.

My cat was really struggling with a urinary problem. She had suddenly started straining to pee every couple of minutes anywhere she could. The most scary symptom was blood in her urine when she did manage to pass any. With vets quoting high prices, I thought I'd try this before resorting to an expensive trip. On only day 2 of taking these there was a massive change in her behaviour. She stopped trying to go every few minutes and started using her litter tray again. She was still going more than normal, but far far less. And the blood in her urine had completely stopped as well. By day 4 she was 100% back to normal. Running around like the silly girl she is. Peeing normally, appetite restored. I'm so thankful I tried these. The vets where looking very expensive and also stressful for both me and my cat. I broke the capsules open and mixed them in with lick treats for her. She was very happy for the treats and didn't even notice she was taking medication. I really cannot recommend this enough. Brilliant product!!

This really does work when your cat has cystitis! I buy it for my cat every year or two because he seems to get it on occasion. Where he can't stop peeing and nothing comes out! Its so sad to watch because they just keep going back and forth to the litter tray! Or they have slight blood in their urine... Be careful though, you must make sure the cat is acting the same and eating and drinking as normal, you'll know the signs when your cat has had it a few times... A tip is to make tuna ice cubes too, its a way of getting more water into their system to flush out the infection. Switch to wet food too until the little fella is over it :) I went to my vet the first time and it cost me £40+ to get the tablets... Now I recognise it and buy they myself, these are the ones the vet prescribed to me. Same quantity and everything! Saves me a fortune and works with my cat every time. I would definitely recommend!
