Sugar

Unlike humans, cats don't have a sweet sense of taste—they simply can't taste sugar. Nevertheless, sugar is found in many conventional snacks, usually as a cheap filler or flavor enhancer. However, sugar is completely unnecessary for cats and can quickly cause health problems. It leads to obesity, promotes the development of diabetes, and can cause tartar and mouth infections.

Grain

Although grains are often found in pet food, cats have absolutely no need for them. As pure meat eaters (carnivores), their digestive systems aren't designed to properly utilize plant starch. Grains can therefore lead to digestive problems such as bloating or diarrhea and are also suspected of causing allergies. Particularly sensitive cats react quickly to grains—which is why our snacks remain completely grain-free.

gluten

Gluten is a protein found in many grains. It's difficult for many cats to digest and can cause intolerances or inflammatory gastrointestinal disorders. Symptoms such as diarrhea, vomiting, or loss of appetite can result. To promote healthy digestion and well-being, we at RumbleBox completely avoid gluten-containing ingredients.

Dyes

Colorings make products visually appealing to humans – cats, on the other hand, don't care about the color of their food. Many artificial colors are suspected of causing allergies, hyperactivity, or behavioral problems in animals. Because we use only natural ingredients, our snacks don't need artificial coloring – they look like good ingredients do: real.

Konservierungstoffe

Preservatives extend shelf life – often at the expense of health. Many chemical additives can put a strain on cats' livers, kidneys, and immune systems. Health consequences can occur, especially with regular feeding. Our products are either freeze-dried or freshly packaged – completely free of artificial preservatives. This keeps everything fresh, safe, and healthy for your cat.

Häufig Gestellte Fragen

What are freeze-dried cat snacks?

Freeze-drying is an advanced technique that involves freezing fresh food at -36°C and removing the water under vacuum, leaving only the nutrient-rich substances. After packaging, the product is irradiated to kill bacteria and ensure the safety and health of your pet.
What are the advantages of freeze drying?

Rich in nutrients: Freeze-drying at -36 degrees ensures that all important nutrients are retained in the meat to meet the basic needs of cats.

Real meat taste: 100% restoration of real meat taste. No need to worry about bacteria, cats prefer to eat it.

No frills: no added preservatives, which also guarantees a longer shelf life.

Emotional Connection: This high-quality snack in chunks is perfect for interacting, training or rewarding your cat. Resealable for easy portability.
What is the difference between “Natural Sliced” and other snacks?

Natural Cut Freeze Dried Snacks are whole pieces of meat that have been processed using freeze-drying technology and cut into smaller pieces or preserved in their whole form. Unlike some other cat snacks, Natural Cut Freeze Dried Snacks retains the natural structure, taste and nutrients of the meat, making it a high-quality snack for cats.
Our Mission

Our mission is to ensure that every cat can enjoy healthy and pure cat treats. By using natural ingredients and high-quality meat, without chemical additives, we aim to deepen the emotional bond between cat owners and their cats and create a healthier, purer lifestyle.Discover more
