Many people are curious about whether or not cats can eat parsley. The answer is yes, cats can eat parsley, but there are a few things to keep in mind. Parsley is safe for cats in small amounts, but it is not a nutrient-rich food and should not be used as a substitute for a balanced diet. Cats who eat parsley may experience some digestive upset, so it’s best to introduce it slowly and in small quantities.

Parsley is a biennial herb that is often used as a seasoning or decoration. It is a member of the Umbelliferae family, which also includes carrots, dill, fennel, and celery. All parts of the Parsley plant are edible, but the leaves are most commonly used. The leaves have a fresh, grassy flavor that can enhance many dishes.

Parsley is an excellent source of vitamins A and C, as well as folic acid and iron. It also contains chlorophyll, which has been shown to have cleansing and breath-freshening properties. For these reasons, Parsley is sometimes used as a natural breath mint or mouthwash.

What is Parsley?

Parsley is a species of Petroselinum in the Apiaceae family, native to central and southern Europe. It is a biennial plant growing to 20-50 cm (8-20 in) tall. The leaves are bright green in color, simple, with bubble-like appearance, 3-8 cm (1.2-3.1 in) long and 2-4 cm (0.79-1.57 in) across. The flowers are white or pale green, 2-4 mm diameter, produced in umbels up to 8 cm (3 in) diameter. The fruit is a dry schizocarp from 2-4 mm diameter, brown or yellowish brown.

Parsley is used for its leaf in much the same way as coriander (which is also known as cilantro), although parsley is perceived to have a milder flavor. In central and eastern Europe and Asia, many foods are served with fresh chopped parsley sprinkled on top. Curly leaf parsley is often used as a garnish on potato dishes such as mashed potatoes. Root parsley is very common in central, eastern and southern European cuisine, where it was know as early as 1650.[citation needed]

In parts of Europe such as Austria, Hungary, northern Serbia and Slavonia (Croatia), roasted duck or goose are traditionally accompanied by root parsley boiled in water and mashed into a puree called “petersilknudeln” or “petersilienpüree”. In Germany it goes by the name “ULEKUDLEN”, which translates literally into onion noodle.

Cats can eat parsley but only in moderation because it contains essential oils that could potentially be toxic to them if ingested in large quantities.

The Benefits of Parsley for Cats

Parsley is a common herb that is used in many dishes, both for flavor and for decoration. But did you know that parsley also has some health benefits for cats? Here are a few reasons why your cat may benefit from eating parsley:

1. Parsley is a good source of vitamins A and C, which are important for a cat’s immune system.

2. Parsley can help to freshen a cat’s breath.

3. Parsley is a diuretic, which means it can help to increase urine output and flush toxins from the body. This is especially helpful for cats with kidney problems.

4. Parsley is also a good source of folic acid, which is important for pregnant cats or cats who are nursing kittens.

If you want to give your cat some parsley, it’s best to chop it up into small pieces so they can easily eat it. You can add it to their food or offer it as a treat. Cats typically love the taste of parsley, so they’ll be more than happy to eat it!

The Risks of Feeding Parsley to Cats

While parsley is safe for Cats in small quantities, there are some risks associated with feeding this herb to your feline friend. The biggest concern is that parsley is a member of the umbelliferae family, which also includes celery and carrots. These vegetables all contain a compound called psoralen, which can be toxic to cats when consumed in large quantities.

Parsley also contains a substance called apiole, which can act as a diuretic and cause vomiting and diarrhea if your cat consumes too much. If you do decide to feed parsley to your cat, make sure it is only in small quantities and always supervised.

How to Introduce Parsley to Your Cat’s Diet

If you want to introduce parsley to your cat’s diet, the best way to do so is to start with a small amount. Add a pinch of parsley to your cat’s food and see how they react. If they show no adverse reaction, you can slowly increase the amount of parsley in their diet. However, if your cat does have an adverse reaction, stop feeding them parsley immediately and consult your veterinarian.


Parsley is an herb that’s safe for cats in small amounts. It can provide some health benefits, such as helping with bad breath and easing an upset stomach. However, too much parsley can cause problems like kidney damage or urinary tract blockages in cats. If you want to give your cat parsley, start with a very small amount to see how they tolerate it.
