Not picking up cats etc

Hey, I have the Video Doorbell 2 and I'm disappointed because it doesn't capture any movement from animals that visit our front garden. We often have foxes and cats visit our front garden but it never seems to capture their motion. The camera captures cars, dog walkers etc on the road no problem at all, just nothing in our garden.. I have it set as sensitive as possible and still no good. My neighbour has the Ring Doorbell as well, and they capture foxes etc so it should be capable. Any help would be appreciated.
