FortiFlow Urinary Support for Cats

  • Pot of 60 Chews £16.99

FortiFlow™ has the same formulation as the previous SettleMe Urinary & Calming Support for Cats. If your cat has urinary issues, we recommend using FortiFlow™.

If your primary concern is stress & calming support, we suggest changing to the new SettleMe Calming Support for Cats & Dogs (pack of 30).

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.

Suitable for long-term use for urinary support, and in a range of situations that can be stressful and may contribute to urinary problems in cats including:

  • introducing a new pet or family member to your household
  • moving home
  • cattery/vet visits
  • parties
  • fireworks
  • thunderstorms and loud noises
  • changes to routine

FortiFlow™ Urinary Support for Cats contains a careful blend of ingredients chosen for their gentle but effective properties, such as N-Acetyl Glucosamine (not to be confused with other forms of glucosamine) which is often used to treat inflammatory conditions and may help protect the lining of the bladder wall. D-Mannose is a 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.

Chews are pyramid 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.

Settle Me Chews

1st Sep 2016
  • VioVet Customer Since: February 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

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.
