In the following video, cat behaviourist Anneleen Bru explains:

  • Why most cat behaviour problems aren't actually behaviours problems...
  • What behaviour we should change in our cats
  • What the difference is between problem behaviour and a behaviour problem
  • What the difference is between normal and abnormal cat behaviour
  • What makes normal cat behavior become an unwanted behaviour for cat guardians?
  • What are different influences on the feline behaviour modification process to keep in mind

Loving your cat isn't enough.
At some point, you need science to truly understand them.

This is what changes when you implement the Cat Matrix in your home:


  • Your cat becomes more confident and searches more friendly contact with you.

  • Your relationship becomes stronger because you become more predictable for your cats. You also communicate more in ways your cats understand and she learns more ways to communicate with you.

  • Stress levels go down because you actively provide your cat with tools to deal with the stress she feels.

  • Your cats are stimulated to show happy body language that causes their general stress levels to go down. Your cats become more tolerable towards each other.

  • Emotions of frustration, fear and anxiety decrease and your cat becomes more resilient.

  • Your cats adapt better to uncertainty and unpredictability in her environment (something cats really don't like!).

  • Undesirable behaviours such as urine marking, house soiling and tensions between cats decrease (sometimes overnight) as cats no longer need this behavior to cope with their environment.

  • Cats with chronic health issues (e.g. FLUTD, FIC, FHS) are emotionally supported which is beneficial for their overall health.

FAQ

  • Does this work for every cat?
    Yes. Every cat is different, but feline behaviour follows clear patterns.

    Inside the Academy, you learn how to understand your cat’s behaviour and apply the right steps from the Cat Matrix to your specific situation.
  • How quickly will I see results?
    Some changes can happen within days or even overnight.

    More complex behaviour issues may take longer, depending on your cat and the situation.

    What matters is that you finally understand what is happening, why it sometimes takes longer, and what to do next.
  • I have multiple cats. Will this still work?
    Yes.

    The Cat Matrix is designed to help you understand both individual behaviour and interactions between cats.
  • Is all the advice based on science or professional experience as a cat behaviour consultant?
    Both.

    All methods inside the Happy Cats Academy are based on science-based feline behaviour principles, combined with more than 15 years of professional, hands-on experience as a feline behaviourist.

    This is based on working with thousands of cats and their owners in real-life situations.
  • Is this suitable for beginners?
    Yes.

    The Academy is designed to guide you step by step, even if you have no prior knowledge of cat behaviour.
  • How is this different from free advice online?
    Most free advice focuses on quick tips and is often incomplete, short-sighted, or only works temporarily.

    Some approaches also rely on behaviour modification techniques that create fear, stress or avoidance, rather than building real understanding.

    Inside the Happy Cats Academy, you learn the underlying, science-based logic behind your cat’s behaviour.

    That means you don’t just fix one problem temporarily, you understand how to prevent and solve future problems, in a way that supports your cat’s wellbeing and creates lasting, cooperative change.
  • Will there be new content added in the future?
    We will continue to add new video lessons on cat behaviour and common behaviour problems.

    With lifetime access, you automatically get access to all future content.

    We’ll notify you by email whenever new lessons are added.
  • Is it really US$99 for lifetime access and all future updates?
    Yes, it really is. No subscription.

    And to be fair, US$99 is a very honest price for the tremendous value you receive.

    That’s a conscious choice we made to support our mission: to make every cat in the world happier.

    We’ve chosen a no-brainer price on purpose, so our Happy Cats methods and Cat Matrix Blueprint are accessible to every cat owner, not just a select few.

    Because all cats deserve to be happy and to become the best version of themselves!
  • Some videos use an AI avatar of Anneleen Bru. Why is that?
    Some of our videos are presented using an AI avatar of Anneleen.

    This allows us to create content faster, in multiple languages, and keep the Academy accessible for every cat owner.
  • Do you have a refund policy?
    Yes.

    If you don’t see any improvement in your cat’s behaviour within 14 days, and you’ve applied the first steps of the Cat Matrix, you can request a full refund.

    Simply email us at hello@happycats.com.
  • How can I contact you if I have questions?
    You can contact us for any questions about your access, payments, or the Academy.

    For personal behaviour advice about your cat, you can book a 1-on-1 consultation with Anneleen (€250 / 60 min) via hello@happycats.com.
