My mom told me something funny today. She makes their dogs' food and the recipe calls for squash or pumpkin. She was using pumpkin for a while. The benefits were multiple: 1. The resulting poo is the color of pumpkin pie filling, making it easy to find in the grass. 2. Said poo is a different color from the local slug population. During her morning rounds of salting the resident slugs, my mom can now avoid salting the orange poo (which she previously mistook for slugs!!).
