Finn vs the neighbour's cat, Kluay the hamster hides

My neighbour got a cat last month and she is always walking on our fence. Finn (our poodle) goes crazy every time, barking from the balcony. This is the 3rd week and Kluay the hamster is also very confused, he runs back to his house every time the noise start. What we do now: Finn is on the leash when the cat is near, and we give him a treat when he stays quiet. The cat is not scared of him so it is not so easy. Maybe in 2 weeks they can sit near each other through the fence. Kluay is fine, he is not in danger. I put a cloth over the cage at noon so he can sleep without the noise. Hamster is a nocturnal animal and he gets angry when I wake him in the day.
