I went to the grocery store to try and find something for Elizabeth (that the raccoons won't eat.) I was looking at the sardines --- (do you know how many kinds of sardines there are!!!! And I've never eaten ONE!!!)
Anyway...sure enough I found clam juice. It was in the juice section. It is surprisingly low in sodium so I bought some to have on hand in case I ever need to get Edwina to drink.
Seems easier than draining a can of tuna!
