Not too sure
Started with a fish one. My 2 cats loved it. But the smell was a bit stong. So switched to the lamb one. First pack was good. Nice smell and my cats liked it. But something went wrong with a second pack I've ordered. They are leavibg the daily porsion. And one of the cats trowing up after eating. Switching to another food only after 5 days of feeding from a new pack. Bit dissapointed, coz never had a problem like this. And was feeding Purizon for past 2,5 months.
