I'm not sure if I should use coffee grounds in the compost. Apparently it's a good slug and cat repellent when scattered through out the garden. There is a local cat that visits my yard and garden area every night. And BTW: It's still cold here this morning. It was 18F when I got out of bed and it's now up to a balmy 35F. LOL! This is supposed to be the last of the really cold mornings. Fingers crossed.
