Well I don't know if my cats are scared of cucumbers. Notice the plural, I now have six cats from 2 liters.
Anyhow I can assure you that they are not afraid of snakes. The matriarch of the clan killed a four foot black snake a few days ago and drug it into the shop. They gnawed off the head but ignored the rest of the body until it bloated up and started stinking before I hauled it off to the ditch yesterday.
