Purchased this for my cat who has skin issues which apparently certain foods and the protein in them can cause flare ups. He hates all the veterinary wet foods that he can/should eat for his issue, & won’t touch the stuff unfortunately. I did some research and duck (as well as lamb) seem to be more cat friendly with issues that my kitty has. He loves this food… for a fussy little fellow, he devours this food every time. Now… we have to see if it treats him (&his skin sensitivity) well. Fingers crossed it work out for him.
