clrose - please take the time to read the website SCM included in her post to you. You will find that there is no dry food that is good for cats. Yes, there may be issues with switching to the wet. Those issues will end once the cats get used to the better quality food. Dry food was not invented for cats. Dry food was invented for owner's convenience.
All it takes is patience and a willingness to stick with it. And a bottle of cleaner.
A good one is 1/4 cup rubbing alcohol, 1/4 cup vinegar, 1 cup water mixed in a spray bottle and sprayed where the offending accidents occured. It takes the smell away so the kitty does not use that spot again later on.
