I read the comment about using a cat to catch the mole, but ask any vet and they’ll tell you moles will sicken and poison cats. The cats can die from ingesting them. The castor bean sounds like a good idea. Same with the tobasco sauce. There are also plant that keeps them away. Just google for that for the various types. But I really wanted to mention that cats do get very sick from eating moles and arent the solution at all. If you love your cat, find a way to get the moles out of your yard.
