I'm in the same shoes as you Furryland. Have 1 cat that will only eat cut/gravy and not pate/loaves.
I contacted Fromm and they said to check with them in the summer, too.
Loopoo - I believe Merricks cuts are only for dogs
Heathr - I googled the Castor and Pollux ones. I live in SK (not sure where Furryland lives) and there are no Petco's here. Says the closest place for me to get them would be in Edmonton. While it is 6 hours away, I think I might be making a trip there soon.
