What animal eats cucumbers?
Small ones are chomped but the large cukes are literally scooped out. We are trying to figure out if it's a squirrel or a rabbit based on those large front teeth. Could the squirrels be climbing a 5' fence and eat cukes one after another? Your thoughts please.
You'll have to catch the critter in the act to know for sure what is eating your cukes. Don't rule out raccoons or groundhogs; those guys can climb fences and dig under them. Critters seek out cucumbers and tomatoes when they need water. The following article on raccoon control will also control rabbits and squirrels. For rabbits, fencing should have holes less than an inch in size. https://www.gardeningknowhow.com/plant-problems/pests/animals/getting-rid-raccoons.htm
