As there is a strong correlation between stress and urinary health, FortiFlow™ is a supplement for both cause and effect; on one hand helping to reduce stress and related behaviours, and on the other, working to support and maintain normal urinary tract function and relieve associated discomfort.

These soft chews have a mild meaty flavour and crumbly texture. If not taken like a treat, they can be crumbled into food and won't overpower your cat's dinner. Purrfect!

FortiFlow™ Urinary Support for Cats contain a careful blend of ingredients chosen for their gentle but effective properties,

  • N-Acetyl Glucosamine (not to be confused with other forms of glucosamine eg. for joints) which is often used to treat inflammatory conditions and may help protect the lining of the bladder wall.
  • D-Mannose is a natural sugar thought to assist in preventing recurrent cystitis by binding to bacteria, and is found in cranberries and other berries, peaches, apples and some plants.
  • Finally, the inclusion of L-Tryptophan - an amino acid precursor to the neurotransmitter serotonin - will help keep your cat calm, happy and contented.

If your primary concern is stress & calming support, we suggest trying our SettleMe Calming Range.

Chews are cylinder shaped, approximately 12mm long and 9mm deep.

Directions for use:

Feed whole either before or after a meal, or mixed into food. Fresh drinking water should always be available. Give for as long as considered necessary or as directed by your veterinary surgeon.

My cat changed her behaviour. She is so much relaxed and she is going to the cat litter with no problem at all.

55 Stressed
Verified Purchase

By on 13 October 2019

Our 14 year old cat had become stressed because our daughter and her 3 year old cat moved into our house. He developed cystitis and was peeing small amounts of pee with blood in it around the house. We bought this product but had concerns that getting the medication into the cat would also cause him stress! Very pleased to report that he eats the whole tablet with his food without any problems. The cystitis has calmed down and all seems positive. Give this a try.

Sorry, she's a very fussy elderly cat and has completely ignored the product so far. Live in hopes!

Royal Canin GI 32 is brilliant and appears to have solved her problem

My cat is pretty fussy, is there any way of getting a small and inexpensive sample before committing to a whole tub?

  • VioVet Staff

Hi Kim,

I'm afraid we don't have a sample pack for this product at the moment, but if you want to give it a go, the 15% off offer will run until the end of this month. The chews don't have a strong flavour, and can also be crumbled easily and mixed into food.

I'd recommend starting with a small amount of the chew (maybe 1/4 and don't show her that you've added it to the food) and build up to giving her a whole one over a week or so, so she can get used to something new.

If you do decide to give it a go and you don't have any luck, just let us know.

Kind regards,

Settle Me Chews


  • VioVet customer since 2016
  • From: Lincolnshire, United Kingdom

I have read the ingredients in the chews and I see that they contain sugar .Is this a different type of sugar than that that is found in some cat foods (which I avoid ) as I have always been led to believe that cats do not need sugar but being a fruit sugar I'm thinking maybe this is ok?
Yours Sincerely
Mrs H Woolley

  • VioVet Staff

Hi Mrs Woolley,

D-Mannose is included for it's ability to bind bacteria that can cause inflammation and damage to the bladder lining, and to bind harmful substances that can cause blockages in the urinary tract. The amount provided in each chew is very small but it is not digested or intended to provide an energy source, so it is safe even for diabetic cats. The majority of D-Mannose is passed out in the urine (where in the bladder it can bind bacteria or toxins) and only a negligible amount is used in the body so it does not affect blood sugar levels.

I hope this is helpful! Please feel free to order a taster pack to see if your cat likes them and let me know if I can help further.
