I am using the petco brand of tuna flakes, is a bit of a pain as there is alot of powder to it, so i use the powder on my little heart patient as a topper... boiled chicken has worked just tonite for all 3 of them.... as Slappy (civvie) will not eat anything new... I boiled 3 thighs, cooled and shredded and froze... the broth, i put in ice trays, dumped in a bag for liquid on the wet (have not tried it yet tho)... trying to find something that is not fish cuz Sugar Bean will consume as many flakes as you will let her... I did buy some other stuff, dried shrimp (did not like), salmon (did not like) real mouse pucks (have not tried)... hope this helps some
