Why should I take part in the walk for Cats Protection?

Two reasons, both are as important as each other:

firstly, to help cats and kittens in need across the country. Your generosity and kindness enables our teams to go on caring for abandoned and unwanted cats and kittens
secondly, for yourself! By taking part in this walk, it can be a fantastic and fun way to challenge yourself and mix up your day to day, get fit and raise vital donations for cats in need. We like to think of it as the good kind of nervous. You’re getting out of your comfort zone but you’ll be having so much fun doing it!
