I just went to their site and reviewed the ingredient list. I didn't see anything untoward in the Premium Pates but stay away from the Premium Cuts in Gravy (I'm sure you knew that already!) - they have tapioca starch in them.
It's always better of course to have the As Fed values but on first blush these look low carb to me. Not crazy about the added colour (why oh why do they do this?) but you find that in many foods. The plus being no carrageenan !
If I could get them up here I'd buy them.
Oh, and ETA - always check the label before you buy. Any manufacturer can change the ingredients or formula without notice. If you see any veggies or starches - peas, corn, wheat gluten, rice - I wouldn't buy it. Note that there are a few that have brewer's rice in them that are still technically low carb, but it depends on where they fall in the ingredient list.
Hope that helps!
