Hintergrund Nachhaltigkeit
If it were up to us, sustainability would not be a "nice-to-have," but a "must-have" that all companies should have anchored as part of their identity. Find out why we think so in our Background report. Here we show you what we do.
Sir Mittens may only be a small company, but we still want to make our contribution and take responsibility for the sustainable use of our resources and our CO2 emissions. We want to show that profitability and climate neutrality are not mutually exclusive.
For this reason, we have developed a sustainability concept consisting of four measures, which together should ensure that you can store sustainably and climate-neutrally with us.

1. With every order you plant 1% tree.

One percent - that doesn't sound like much at first, but that one percent has a big impact. We plant trees with Treedom. One tree is paid off every 100 orders. On average, a tree costs just under 20 euros. So 20 cents per order goes into the project.
Compared to other reforestation projects, the prices are quite high. This is because Treedom does not simply plant the trees, but also supports small-scale farmers to care for the trees during their first years of life, when they do not yet bear fruit. The trees are planted, cared for and they will stand permanently. Treedom certifies that each tree becomes and remains a tree.
The small farmers are independent custodians of their land so that they can benefit economically from the project. The price also includes training and thus the creation of income opportunities directly on site - for example in Nepal, Kenya, Haiti, Cameroon, Thailand, Senegal, Honduras or Argentina.

Compensation for the annual shortfall and a health check of the trees are also included.


Treedom plants in small-scale agroforestry systems. This means that much emphasis is placed on biodiversity of native plants and sustainable use of resources and soils. Plant species are selected with strict consideration of local environmental issues, project objectives, and the needs of local communities. And of course the trees bind a lot of CO2.

With this planting concept, Treedom achieves 10 of the 17 Sustainable Development Goals (SDGs) of the United Nations 2030 Agenda. For more information, click here.

The special extra at Treedom is the gamification approach. Treedom not only gets the small farmers and local communities on board, but also the paying customers.


You can plant the trees virtually and/or give them away. Each tree gets its own profile page and is geolocated and photographed when it is planted. In addition, there is a tree diary function with regular updates on the small-scale farmers and agroforestry projects on site.

Every 100 orders we will raffle one of our trees on Instagram and give it away to the winner! The lucky person will be the official godfather of the tree.
You can find our Treedom profile here. We started the project at the same time as the opening of our online store in April 2021. For more information and updates, check out our blog.
Of course, there are other great reforestation projects, for example the Mountain forest project or Eden Reforestation Projects, which mainly rely on favorable mangrove species that can store an extremely high amount of CO2.

2. Our website is climate neutral.

Surfing or streaming on the Internet causes very high amounts of CO2 because of the huge amount of energy it consumes. "If the Internet were a country, it would have the sixth largest electricity consumption in the world," says a Greenpeace expert on energy.
We have therefore made our website climate neutral with ClimatePartner. This means that - measured by our page views per month - we donate a certain amount each year to the climate protection project in the Virunga National Park in the DR Congo.

The project will operate a small run-of-river power plant that will generate electricity for 30,000 residents and connect 5,000 households and many small businesses to the local power grid.

This is intended to prevent the illegal overexploitation of charcoal. Charcoal was previously the only source of energy. In the meantime, a second run-of-river power plant has already been put into operation in the region.

3. We ship with sustainable materials only.

When retail companies order packaging materials, far too many of them go by the principle of "the cheaper the better". After all, the less one has to pass on to their clientele in terms of packaging materials, the cheaper one can offer shipping costs and the better one comes out on top against the competition.
As a result of our consumption, 72 kilograms of packaging waste per capita end up in the garbage can every year - and the trend is rising (source). 44 percent of this is cardboard and paper.
The situation is very bleak when it comes to plastic waste. Germany's recycling rate for plastics is just 5.6 percent.
To avoid destroying more large amounts of trees and creating even more plastic waste that ends up somewhere in the oceans or in completely overburdened third countries, we use sustainable and plastic-free materials.
  • We ship with compostable paper padded bags without plastic content. They are made of 100 percent waste paper, i.e. recycled paper.
  • No new trees had to be sacrificed for our Maxibrief boxes either. They are made of 35 percent local dried grass and 65 percent recycled paper.
  • Larger boxes have a high grass content of 35 percent. The grass comes from regions of unused pastures.
  • Our tape is silicone-free paper tape that can be disposed of with waste paper. The adhesive material is natural rubber adhesive.
  • Our filling material is grass paper paper wool.
This packaging material is not yet perfect, but according to our research it is the best available at the moment. However, we are happy to be taught better and are also constantly keeping our eyes open ourselves.
Our shipping bags and boxes are high quality, sturdy and too good to throw away directly. Please reuse them!

The shipping bags and boxes are on average significantly more expensive than conventional packaging. Nevertheless, our shipping costs are at a normal level of 3 euros (shipping bag) or 5.90 euros (package) within Germany. From 50 Euro purchase value we can even offer shipping free of charge (within Germany).
We only use non-sustainable cushioning (e.g. bubble wrap) in absolutely exceptional cases and only when there is a high risk of breakage and the value of the shipment is very high (e.g. Meissner porcelain). When we do use them, they are reused bubble wrap. As soon as we have found sustainable alternatives that offer equally high protection, we will of course adapt this.

Germany also has the Packaging Act to increase recycling rates and reduce the impact of packaging waste on the environment. Under the law, all companies must pay a license fee for packaging when it is first put into circulation. We have licensed our packaging from Grüner Punkt and are therefore also allowed to use the online label.

4. Emissions not created are the best emissions.

With the first three measures, we are only compensating for what we cannot prevent. Of course, this can only be part of the solution. The best solution is to prevent emissions from occurring in the first place.

To do this, we have to change our behavior to a large extent. That won't happen overnight, but we're working on it, too. For example, we hardly eat any meat anymore. If there are plastic-free packaging alternatives (e.g. jars) in the supermarket, we choose them. Food that we buy, we also consume. And yes, unfortunately, we don't always manage to do that.

We take trains for longer distances and take public transportation or bicycles for shorter distances. We wear our clothes for long periods of time and use our smartphones not just until a new generation is out.

All of these - and many more - are small things we can change in our everyday lives. As trite as it sounds, a global catastrophe like the climate crisis can only be overcome together. We can all make a difference.


One last request

You have a statutory withdrawal period of 14 days from the date on which you received the goods. More about this in our FAQ. Nevertheless, we would like to ask you to order from us only if you are sure that you want to keep the products. We spend a lot of time describing the products in great detail so that there is no disappointment on your side. This way we want to reduce returns to an absolute minimum. So with your cooperation we save avoidable transportation.
We are aware that some people say that returns for a fee are not customer-oriented. But we think that this is a reasonable regulation in favor of our environment. Small restriction, big benefit!
Besides, we think our customers are very smart people. After all, they love cats. We believe that we are all capable of making sensible and well-considered purchasing decisions. And if something does go wrong, please feel free to contact us.
We'd love it if you feel the same way and support us in our mission!
