About Me

I’ve been fascinated by cats since I was a kid – it all started when my family rescued an injured stray cat.  From then I was smitten. 


I initially trained as a psychologist but found myself drawn to use my psychology to help cats and their humans.  Studying Clinical Animal Behaviour got me on the road to becoming a cat behaviour geek and I’ve never looked back. 


Helping cats adjust to huge changes in their lives, and supporting them to find ‘purr-fect' homes during my time as Feline Welfare Manager at Battersea Dogs and Cats Home (browse their website), helped consolidate my passion for cat welfare. 


Battersea haven’t been able to get rid of me completely as I’m still one of their Battersea Academy facilitators and will soon be helping them with their cat behaviour advice line for customers.


Here’s a short video of my time at Battersea:

Creating cat content online (e.g. my Stray Mogs column) means I also get to help cats and their humans without actually meeting them.



I’ve got these professional accreditations along with my psychology and clinical animal behaviour qualifications (a BSc, an MSc and a PGDip):


  • Chartered member British Psychological Society (browse website).

  • Provisional member* Association of Pet Behaviour Counsellors (browse website).

  • Candidate member Fellowship of Animal Behaviour Clinicians (browse website).

  • Working towards Certified Clinical Animal Behaviourist (CCAB) status (browse website).


You’re probably wondering whether all this really matters.  But actually, yes it does.  This means I’m ideally placed to understand your feline’s mind, their behaviour, and what’s going to help them live their best kitty life.  But don’t worry, I’m not all about theory, I’m also into the practical stuff too.


So, if you want to know you’re doing everything you can for your cat so they can thrive and don’t mind spending a bit of time taking action for your cat, get in touch.   


By the way, I’m covered by specialist professional insurance and have an Enhanced Disclosure and Barring Service (DBS) check.  If you’d like to see proof that I’m covered or evidence of anything else, just let me know.
