Well tonight I gave them the ground up stuff from the morning with a bit of shredded cheddar in it. Maggie ate a bit of it as she was soooo hungry. Hot Rod picked the cheese out and ate a couple of bites of it.
I then squeeze some fish oil from a capsule on the food and the little booger gobbled it up! I had been giving it to them a while ago (per the vet) and he got tired of it so I stopped. I'm going to keep this up and see how long this will last. I've got almost 2 full rolls of the lamb and beef flavored NB Rolls in the freezer so I'm hoping that this will help with him eating it! Keep your fingers crossed for me.
I appreciate everyone's suggestions!
