Collection: Supplemental food for cats

Cat supplements are for those who want to do a little more for their cat's everyday life. It's not about making feeding complicated. It's about supporting the cat where the need arises. At FjeldgaardShop, you'll find cat supplements selected with a focus on quality, function, and practical solutions.

Some cats need extra support during certain periods. This could be, for example, during shedding, with old age, due to changes in routine, or if the cat has a more sensitive stomach. Other cats benefit from a supplement as part of a stable and well-considered daily routine. The most important thing is not to buy as much as possible. The most important thing is to choose the right product for the right need.

At FjeldgaardShop, we select cat supplements with a focus on well-thought-out solutions and proper quality. The goal is simple: You should be able to find products that suit your cat and work in everyday life.

Free shipping on orders over DKK 499. Delivery 1-3 business days for in-stock items.

Complementary feed for cats, when you want to optimize well-being without changing everything

Food supplements are the easy shortcut to support your cat when you notice that there's an "area" that needs improvement. This could be dry fur, a sensitive stomach, stress due to changes, hairballs, or a senior cat that isn't moving quite like before.

The important thing is to say it as it is: Food supplements are not magic. But they can be a really powerful tool if you choose correctly and use them consistently.

What is supplementary feed for cats

Supplements are products given in addition to a cat's regular complete feed. These can be oils, powders, tablets, pastes, or treats with a functional effect.

Rule of thumb, which has always applied:

  • Complete feed covers basic needs
  • Supplements support a specific need

If your cat has an illness or medical problems, you should always use supplements in consultation with a veterinarian.

The most popular types of cat supplements and what they do

Here are the classic "categories" that cat owners typically shop for.

Coat and Skin

Typically fish oil or fatty acid products. Often used for dry skin, dull coat, and shedding.

  • Good for indoor cats and cats that shed a lot
  • Also relevant during seasonal changes

Joints and Mobility

Used especially for seniors or cats that seem stiff after rest.

  • Relevance increases with age
  • Often requires longer use before you see an effect

Stomach and Digestion

Probiotics and fiber products are classics for cats with sensitive stomachs or fluctuating stool consistency.

  • Good for food changes and stressful periods
  • Stability is key

Hairballs

Paste or fiber supplements that help the cat pass hair through the system.

  • Particularly relevant for long-haired cats
  • Also relevant for excessive licking

Calmness and Stress

Supplements for nervous cats, transport, new home, new family member.

  • Perfect as support during a transition period
  • Often needs to be given well in advance of the "situation"

Urinary Tract

Often used as support for cats prone to urinary tract issues. Here, it is extra important to choose quality and follow dosage.

How to choose the right supplement without wasting money

If you want to choose effectively, here's how:

  1. Choose one focus at a time

    If you buy three supplements at once, you won't know what works.
  2. Look for a simple ingredient profile

    The easier it is to understand the content, the more control you have.
  3. Choose grain-free and gluten-free when it makes sense

    Many supplements are naturally grain-free and gluten-free, but not all, especially if they are "functional snacks". Always check.
  4. Produced in the EU is a plus when you are looking for stable quality

    Traceability and consistency matter, especially if your cat is sensitive or you use supplements for longer periods.

My honest opinion: Rather one good product for 6-8 weeks than five mediocre products for 10 days.

Dosage and use, here many cat owners typically make mistakes

The classic mistakes:

  • Giving too much "just to be safe"
  • Changing products after a week because "I can't see anything"
  • Mixing everything together at once

Good habits:

  • Start with the recommended dosage
  • Use it daily for the recommended period
  • Keep an eye on changes in fur, stool, energy, and appetite
  • Take breaks if the product is designed for a course of treatment

If the cat gets loose stools or becomes unwell, stop and go back a step. It's simple management.

When does supplementary feed make the most sense

Supplements are typically a very good purchase when:

  • your cat is a senior
  • you observe dry skin, dull coat, or excessive shedding
  • the cat tends to have hairballs
  • the stomach is upset
  • the cat is affected by stress, moving, or transport
  • you want to support specific areas without changing the complete feed

Topping and animal welfare, better choices in practice

When we talk about responsible choices, it's about raw materials, transparency and quality. Topping can be a way to provide a more varied diet without overconsumption. It can also be a way to use more "clean" ingredients rather than chasing the latest hype.

If you care about animal welfare, look for:

  • clear ingredients
  • proper declaration
  • manufacturers who take quality seriously

Who benefits from extra topping?

Topping may be relevant to many, but it is especially obvious for:

  • picky dogs
  • senior dogs
  • dogs to be taken
  • dogs that need more fluids
  • dogs during training periods where appetite and energy fluctuate
