Hmmm....BraveHeart must have been 'trained' in his long-ago home!

I'd check with the vet...processed stuff like deli turkey (if it's 'turkey roll') might be high in salt.

If a grocery store has those bbq'd chickens, getting one or two of those would be economical - take off the skin, chop up the meat stuff, and freeze what you can't use.

Also - rinsed and drained tinned salmon and tuna. Un-tinned shrimp - hopefully you can get a generic bag of pre-cooked for not too much money. (That's just for treats!)

Also...raw stewing beef cut into tiny soft bits, or raw burger. Burger that is fairly high-fat might be a good thing, unless his liver or kidneys indicate otherwise.

Hmmm....ground beef liver....high in iron!

What a hopeful sign!
