Pet behaviourist

Also non-Dutch dog and cat owners can ask me for help.


Who am I?

My name is Merel Van der Mullen, born in January 1992 and living in Maastricht together with my partner Ward, 2 cats named Hunkie & Amy and my horse Marley. Personally, I have always liked having animals around me. My love for animals remained when I grew up and therefore I started at a vet-tech study, which I successfully completed. Afterwards I followed another higher education and university study human health, but this was not living up to my expectations. In 2014, I was able to start work as a vet tech and I encountered a cat behavioural expert. That made me decide that I wanted to broaden my knowledge about animals in terms of behaviour. After completing the 2-year study “BSc Applied Animal Behaviour” at University Centre Sparsholt in 2017, I received a specialization in dogs and cat behaviour.


Behavioural expert & pet sitting – dog walking service

In July 2016, I founded my behavioural expert practice in the area Maastricht, Heerlen, Sittard and the Belgium side of Limburg. Later in 2017 I expanded my practice with a pet sitting and dog walking service. You can find more information on


How do I work?

Understanding the behaviour of the animal comes first during the treatment plans. An animal never “just” does anything; literally, there is a reason for everything it does. It is up to us to find what specific reason the pet has and to transform unwanted behaviour into desired behaviour. For this to happen, we have to learn how to “read” an animal. With every position of the body, head, ears, eyes, tail etc. an animal tries to tell us something and I will teach you how to recognise all that.

Changing behaviour takes time and a quick fix never fixes the underlying issues. If you’re experiencing unwanted behaviour we have to understand that this behaviour did not appear in just a day. It took several weeks, months or even years to develop. To undo unwanted behaviour cannot be solved in 1 day.

My working method is gentle and kind for the animal. I will explain to you how your animal is feeling and why it is feeling like this. Problematic behaviour often arises from fear, but we must recognise fear. By initially giving an animal the space to observe the situation, it can think about how it wants to respond.
