Feliway Cystease (previously Cystease S / Cystease Advanced) is a tablet given to cats to help encourage urinary health. As stress is considered the main factor in urinary health, it is recommended to use alongside the Feliway calm-inducing diffusers which are available from VioVet here . Various factors have been recognised as being associated with the urinary problems, such as obesity, dried biscuit diets and stress due to environmental factors (often from other cats). Feliway Cystease also contains Hyaluronic Acid and L-tryptophan. Hyaluronic Acid provides further help to the lining of the bladder wall, whereas L-tryptophan has a calming and de-stressing effect on cats generally. The results are even better if Cystease is combined with the pheromone calming effect of a Feliway Diffuser which can be bought separately and used at the same time....
