Over the long weekend, our cats caught four moles. Moles use their front facing paws and claws to dig and eat mostly earthworms which they paralyze with a toxin in their saliva. They live their entire lives underground except when they leave the nest in early adulthood to find their own homes. It may be that these moles were searching for a new home when our cats got them. We don't generally see moles, but I'll be watching for them now.
