Preheat your oven to 180°C
In a bowl, add your fish, along with the liquid and egg and blend using a hand blender or food processor.
Add the flour and stir until a dough is formed, then roll out on a lightly floured surface to 1cm thick.
Use a cookie cutter to cut out shapes - the more festive, the better!
Place the treats on a lined baking tray and put in the oven for 20-25 minutes until golden brown
Remove from the oven and leave to cool before allowing your kitty to enjoy
