About Us

Katz & Mouse is a young and passionate baby clothing company based in London, UK. Our journey started with a simple vision – to create something special that reflects our values and makes a positive impact on the planet.

At Katz & Mouse, we take pride in our commitment to ethical and sustainable manufacturing practices. That is why we are using 100% organic GOTS certified Egyptian cotton for all our products. In addition all other materials used in  manufacturing  adhere to the Oeko-Tex Standard 100, Product Class I standard. These choices not only guarantee the highest product quality but also ensures our products are free from harmful chemicals and pesticides. As parents ourselves, we understand the paramount importance of providing our little ones with clothing that is gentle and safe. Organic cotton boasts superior quality, with long-staple cotton fibres that make it exceptionally soft and durable.

We focus on crafting baby essentials with stylish appliqués and prints that are not only adorable but also designed to last. We want parents to feel assured that when they choose Katz & Mouse, they're investing in products that can be cherished and passed down through generations.

Transparency and honesty are the cornerstones of our values. We believe in being open about our processes and materials, so our customers can make informed choices. We're passionate about staying true to our ethical principles and building a relationship of trust with each and every one of you.

Our choice to use GOTS certified Egyptian cotton is just one step toward being environmentally friendly. We're continually exploring ways to reduce our ecological footprint and make positive contributions to the planet we all share.

As we continue to grow, we want you to know that every purchase you make from Katz & Mouse supports our mission to create a better, more sustainable future for babies and their families. 

Thank you for being a part of our journey. Together, we can make a positive impact and create a brighter future for the next generation. We invite you to join us on this exciting adventure of ethical, stylish, and lasting baby clothing that is made with love and care.
