It’s no secret that plants have beneficial effects on urinary health. This is well known to us, and we consume them as herbal teas. They can also help our dogs and cats maintain good urinary health.
Top of the list is a plant from our regions named for its effect: the dandelion (*Taraxacum officinale*). Its diuretic properties are particularly valuable. It also provides inulin, known to support digestive microbiota—now recognized as central to the body’s balance—as well as potassium, essential for overall well-being. In vitro studies suggest dandelion may also help inhibit the formation of certain urinary crystals!
Cranberry (Vaccinium macrocarpon), a relative of our bilberry, has been the subject of numerous studies in recent years, in both dogs and cats. Among its benefits, it may help limit the adhesion of certain unwanted bacteria to the urinary mucosa, thus supporting bladder and ureter health and balance.
In cases of idiopathic cystitis, emotional imbalance is often a factor. Here again, the plant world can help soothe our cats. While valerian (Valeriana officinalis) may calm some cats, it can have a stimulating effect on others, counteracting the desired outcome. This is why passionflower (Passiflora incarnata) is often preferred for this species. Its calming properties are thought to stem from enhanced use of a central mediator, GABA. Another plant, griffonia (Griffonia simplicifolia), is also highly beneficial for this purpose. Thanks to its high content of serotonin precursor—the well-known neurotransmitter involved in mood regulation and associated with feelings of well-being—its bean-shaped seeds provide a calming effect. Studies have shown that felines can utilize this precursor from a very young age.
While cats are obligate carnivores, they may consume plants in the wild and derive benefits from them. Some are now widely used, particularly to support urinary tract health and complement medical treatment for certain lower urinary tract conditions.
